Windows 7 Mapped Drive Latency With Slow Green Progress Bar And Red X
Dec 13, 2010
We are having ongoing problems with Windows 7 and mapped drive latency on our network. Our environment is as follows:Multiple servers running Windows 2008 & 2008 R2, some VMware servers (including our file server). Windows 7 x64 came preloaded on a brand new Lenovo think-pad, 4gb memory. This occurs on 4 different laptops. This problem ALSO occurs in exactly the same way on an HP Compaq x64 desktop running Windows 7 32. All systems are fully patched & up to date on SP's. Running IP 4 & 6 on all servers & Windows 7 machines Connected to GB Cisco switch.We run login scripts via GPOs that map drives (with net use commands) to 3 shares on our file-server, drives G, H and S.A fourth mapped drive to an IBM I-series does NOT experience these issues.
In Windows Explorer, mapped drives may or may not appear with red X's, but when clicked on they hang with a spinner and the green bar at the top of Explorer begins to run. This occurs randomly, but usually not right after boot up. It can take over a minute to complete. Also, in Word, which has references to these drives in file locations, file opening and saves can be very slow as it attempts to access these shares.This issue has delayed our roll out of Windows 7.Its unacceptably slow and cannot be used in a production environment.We have tried every suggestion we can find on the Internet:Turned off auto-tuning, indexing, thumbnails, set auto-disconnect to the max (both 99999 and ffffffff). Server & clients. No luck. Changed properties on the mapped drives to optimize for documents...no change.Changes setting on the network cards to disable flow control, set static link speed & duplex. Network drivers have been updated. Even tried using our wireless network and disabling wired connection...no change.All bios and hardware updates are completed...no change.Turned on and off network discovery..no change.
Disabled SMB2 on servers & clients...no change.Disabled firewalls, and unloaded antivirus (Trend)...no change.Safe boot with networking & clean boot with no services other than Microsoft...no change.

I downloaded the DPC Latency checker and I've been getting a lot of spikes. When I open my laptop and start the checker, it's all green; but as soon as I open Chrome or Firefox it starts to spike. It's spiking as I'm typing this. It's reached 65,795. I've disabled devices to try and find the cause but I can't figure it out.

Clicking on a large folder in Explorer can cause a slowly-moving green progress bar. In some cases this can take several minutes to complete.
A common cause is thumbnail caching of image and video files, resulting from having properties | customize | "optimize this folder for:" set to pictures, vs documents or General items.
The most likely solution: in Explorer, right click on folder, select properties, customize, under "optimize this folder for:", select either General items, or documents. Set check box "Also apply this template to all subfolders", then click apply.
The slow progress bar is apparently caused by Explorer scanning the folder and all subfolders to pre-render thumbnail images for image and video files. This happens if the "optimize this folder" setting is pictures or videos. This happens when merely clicking on the top-level folder.
If "optimize this folder" is set to documents or General, the thumnails are not rendered until you actually click on the folder or sub-folder containing those.
This was discussed in another thread on this forum, but it was full of speculative remedies, and the actual cause and remedy was not posted until the last thread (and one year after the thread was started): Accessing drives in Windows Explorer takes a long time I'm creating this thread with a more exact title and concise description, to aid in finding the solution based on a symptom search.
While the above is the most likely cause of a slow Explorer progress bar, there are other possible causes. These include clicking on a remote folder on a slow network, general slowdown due to indexing, disk drive or filesystem caching disabled, disk drive retries due to impending hardware failure, corrupted video files or codec, etc.

When I access my Music files (2600 files, 185 folders, 20GBs) on my Samsung (D) drive I get this slow green line in the address bar going from left to right, takes like 15 seconds to go across, I'm assuming it's indexing(?) the music folder and can't really do anything until that green line finishes going across, is there something I can turn on or off to speed up the "green line" so I do not have to wait the 15 seconds? Would a SATA 6.0 drive help speed up the "green line"?

This hard drive is a SATA hard drive, isnt the only hard drive in the computer, and ive formatted it to NTFS with GParted. I rebooted, got the Windows 7 installation running, choose the hard drive and it says it cannot install on that hard drive. I tried formatting it with the Windows 7 installation tools

Windows 7 Home Premium - fully updated. I mapped a drive Z: and disconnected it but it still appears. Nothing I have tried works. I have tried net use many times (with everything else closed down) as follows:
net use z: /delete
net use \sharenameUsers
net use z: \sharenameUsers /delete
net use z: \sharenameUsers * /delete ( ie.I passworded the map)
net use z: \sharenameUsers myactualpassword /delete
Yes I rebooted after net use. Yes I used the actual sharename not \sharenameUsers. Is my net use syntax correct for a passworded map?

When I upgraded from XP (a long time ago) I deleted all the thumbs.db files. I can see thumbnails on my local C: drive. If I browse my network drive I can see thumbnails.
But I have also mapped my network drive as Z:. If I browse the mapped drive I can't see thumbnails.
Can anybody confirm that they can/cannot see thumbnails on mapped drives that don't contain thumbs.db.
Folders don't initially incorporate Folder.jpg into their thumbnail. If I browse into the folder I can see the thumbnail for Folder.jpg only. If I then return to the parent folder the folder now incorporates Folder.jpg into it's thumbnail.

I run a small network in my business. The software I use is perfectly adapted to my use, but it is written in DOS Basic. This limits my access to network devices.
Until now using windows XP, I solved this problem by choosing one hard drive (C) as my server drive and mapping a (Z) virtual drive in every computer to that (C) drive.
I can access and update info in the server (C) drive from any computer, once I have shared and established permission levels. I share the root of the (C) drive, so everything is accessible.
Now I try this with Windows 7 and I cannot access the server (C) drive from the virtual (Z) drive from my programs, although I can see the (C) drive when I open the (Z) drive.
I have tried every possible level of permission settings, and still no luck. My question is this ...am I missing something here, or is it just impossible to do this in Windows 7?

I run some CAD and compiler software that (unfortunately!) uses absolute path names in project files, so I need to access all my files with exactly the same path for my PC and my laptop. Enventually I want to put all files on an external NAS drive, but only have the PC at the moment.So my first thought was create a folder on my PC, say C:X_Drive, map it as a network drive, say X:, and share the folder as X: on the laptop. Then I'd always access files through the mapped drive, and all paths would be consistent, and moving to an external drive should be trivial.
This sort of works. I've set up the Security tab to give everyone full access. I can read and write the folder itself, but cannot write to the mapped drive version on the same PC, I'm warned I don't have permission. I'm an administrator and the only user on the system. I've tried UNC addressing and direct fixed IP addressing when mapping, no joy. Subst doesn't work properly either (drive comes up as disconnected in explorer, but I believe that's a known Windows bug).

I use the subst command to map my d:downloads to A:
In windows XP recycle bin moved any deleted files from A: to the bin, but in windows 7 it doesn't. I can drag the files from the a: to the destop or another drive, then delete them from there to be stored in RB (just in case i need to restore them) but anything deleted from the A: is just deleted.
any ideas how to make the RB recognise a mapped (virtual) drive?

I'm using XP. I have mapped a network drive to a Windows 7 computer as administrator. I am trying to navigate to Z:UsersMaryPicturesMary's Pictures. But when I navigate to Z:UsersMaryPictures I don't see "Mary's Pictures". I can see "Mary's Pictures" if I'm at her computer.What do I have to do to see all folders and files on Z?

I have a mapped drive that goes to a folder on my internal drive. when my computer starts up the drive will not connect automatically, but connects as soon as I click on it.
I have tried to recreate this drive a few times and always click re-connect on logon but it does not help.
It did work fine for a period so I presume i have done something to stop it working, but can't think what.
I think it may be a setting in my start up configuration (I manage this through CC Cleaner), but can't see what i've switched off.
any ideas?

On startup, I get the message shown below. If I open Explorer the network drive is shown with a red "X" through it. If I click the network drive, it connects and displays the contents without an issue. If I run any application that needs files on that drive before clicking it in Explorer, it will say the resource is unavailable.
What appears to be happening is Windows tries to reconnect to the drive before the network connection is reestablished. I believe this to be the case because the network icon in the system tray is still showing the animation for establishing the network connection when the message pop's up. There is no issue with authentication or password's, etc., as the drive connects as soon as I click on it.
My question is, does anybody know of a way to set the mapped drive reconnection farther back in the boot sequence or add a longer wait state to it so it doesn't time out before the network connection is reestablished.?

Ok, here is a problem I have been having lately and it is driving me crazy. I have a network with a server running 2008 Standard R2 and 4 workstations using Windows 7 Professional 64-bit. I also have 1 other station using Windows XP Professional. The software I run off the server is installed as a client install on the workstations and have to use a mapped drive of E: to let the software see the database. Every 6 to 8 hours of non use of the software... when I reopen it I get a not responding and it has to close and reopen. I looked at the mapped drives and the E: drive disconnects but after opening the E: Drive up it connects right away and then the software works fine. I have tried a lot of things people are saying online. I have disabled autodisconnect -1 in the registry and turned off power management on the Ethernet port. I get the following message when I look at the event viewer.
Event 1005, Application Error"Windows cannot access the file for one of the following reasons: there is problem with the network connection, the disk that the file is stored on, or storage drivers on tihs computer may be missing."But here is the kicker... The windows XP Professional works all the time with no problems so it has to be Windows 7. I have the IPs static in the NIC properties and using the DNS of 8.8.8.8 and 8.8.4.4 which is Google. I was using 192.168.0.100 which was the IP of the server but that didn't make a difference.I gave a lot of details to weed out the normal postingAlso I have DHCP and DNS turned on the server if that would be any possible issue that is causing. I don't know beings I put Google as the DNS if routing in the software would be an issue?

I have the problem of a long list of redundant mapped network drives without drive letters, for example, documents, documents~1, documents~2, etc. all with same location...right clicking on the mapped does not present any "disconnect" option.Oh, they do not appear as mapped network drives under "My Computer," but under "Network" and the name of the computer (which is on a wireless network with another computer)...I can go to advanced sharing and stop sharing, but then all folders are unshared including the original...I guess this may be the only way of getting this corrected, but it seems like a long way to do something that should be very simple..

1. Two Windows 7 computers.
2. Each computer has a user account with the same name, but different passwords.
3. This is necessary because other users can log on remotely to one machine with this user account, but should be locked out of the other.
4. A local user who has access to both accounts tries to access a mapped drive on one machine. The user names are the same, but the passwords are different. Windows gives an error; the local user enters the credentials correctly (same username, but remote machine password) and says "Remember these credentials."
5. Credentials are remembered throughout the duration of the computer session.
6. When the computer is rebooted, the computer forgets the credentials for the mapped drive, and Step 4 starts all over again.
How can the local user save the remote credentials permanently? And is it possible without using Group Policy Preferences, as he is not on a domain?

I have a External PVR unit that is connected to our home Theatre system and we watch downloaded movies that are stored on it's hard-drive.. This box is also connected via UPNP and I can see ALL Drives attached to my laptop which is located upstairs in the study...I was able to, from the computer, map this drive (N Drive) and was able to copy the movies files directly to the hard-drive of the PVR.Until recently, I was able to create new folders on the PVR hard-drive and then copy the files, but am no longer able to do so as I keep getting an error msg stating:"Could not create new file N:Moviesxxxxxx. The system cannot find the file specified"I can however copy the movie files or any other files directly to the hard-drive (ANY FOLDER).. Just cannot create any new folders!!!! Which I was able to do previously.?
P.S. I am running Windows 7 Ultimate x32 on a Toshiba Satellite Pro P300

I have a windows 7 desktop with an SSD and regular mechanical hard drive where I keep my data. I also have a laptop with a small SSD as well. I want to keep the laptop free of non-critical data so I decided to setup a file share between my desktop (Windows 7 home prem) and my laptop (Windows 7 pro). I was able share the files and navigate to my desktop through my laptop. I successfully mapped the folder as a network drive and all was well. Then I rebooted and I was disconnected from it, it remembered that it was there but I needed to manually connect to it and I needed to provide my login credentials. There is no password just a username. Also is there a way to set a timeout because if my desktop is not on and I want to use my laptop, the boot times are much longer compared to when I don't have the mapped network drive on my laptop at all.

I've read that with the mklink command one can create symlinks in windows to mapped network drives. still, whenever I add such a drive as a parameter to the command, I get the error "the file or directory is not a reparse point".What could be the problem? Is there another way to create a symlink on a network destination?

I have a problem with the speed of my mapped network drive. At first al is wel and file loading is as fast as to be expected. But after some time the transfer speed drops dramaticaly and it becomes very slow. I tested it primaraly with loading of image sequences, but it affects all file loading the same. If I logoff and login to windows again the speed is back to its full potential. And then after some time again it drops. I have seached the internet for similar ploblems, but could not find this kind of problem, only the dropping of the connection entirely, but thats not the case here.
All user PC's that have the network drive mapped are windows7 Pro PC's with gigabit lan. The server PC is also windows7 with quad gigabit lan, teamed to 1 connection. A 4 ssd raid setup via a MSI megaRaid controller provides the drive for mapping. The switch is a HP proCurve 1810G-24. Jumbo frames is disabled on all devices. Because i have no domain, the password protection for file sharing on the server is disabled, so al user PC's can connect to the mapped network drive with their own username.
Is there some sort of idle timer on the mapped network drive that could be responsible or something?

I am running virtual XP mode in WIn 7. In XP I am able to map a drive G: that is from Win 7 mapped drive (Microsoft Terminal Services). Great, in Explorer you can see the mapped drive.I need to set up an ODBC connection to a database on that drive. No problem I thought.When I need to select a drive in the Select Database window, I cannot see that drive, only A:, C:, D: , the default drives, G: is not shown

I'm already asking me a while wether it's possible to deactivate the annoying security warning ("Do you want to run this file") when I run exe files on my samba share.
I put various portable apps there and i want to use them as usual files on the local computer. Is that possible? I don't know exactly for what keywords i should search, so i didn't find anything yet. Thanks, best regards, kappen
