Windows 7 Clients Intermittently Unable To Resolve Host Name Of Server
Feb 20, 2012
We have 2 x Server 2008 R2 domain controllers and 120+ Windows 7 x64 clients. We have a print server which runs Server 2008 R2.We have several other servers which also run Server 2008 R2. An issue occurs intermittently and apparently at random, whereby a client will be unable to resolve the host/computer name of the print server. When the issue occurs, we have confirmed the following: - The client has a valid IP address.The client DNS server addresses are correct. - The client can ping the IP address of the print server. - The client can resolve the IP address of the print server by using nslookup and the server�s FQDN. - The client cannot resolve the IP address of the print server by using nslookup and the host/computer name of the print server.The issue can occur regardless of which domain controller the client used to log on. - When the output of ipconfig /display is printed to a text file, many of the other servers in our domain are present in the DNS cache but the print server is not. After the ipconfig /flushdns command is executed, the client can resolve the host/computer name of the print server immediately.
My internet isn't working too well, it shows great signal strength and says its connected but won't let me access the internet. It works if I reset the router but I keep having to do this as it only works for a limited amount of time sometimes for 5 minutes sometimes for 5 seconds. I keep getting this message when I try to access the internet:Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS address.
I'm assisting a client that is running a fully patched SBS 2003. 5 computers on domain; 2 are XP, 3 are windows 7 professional 32-bit.
All 3 Win7 PCs are new HP 6200 SFF, fully patched.
The Windows 7 PCs take a long time to boot up.. it's 3 minutes before the login screen comes up, and after authentication its 2 more minutes before the desktop is up. Once logged on, local network browsing is very slow as well (30 seconds to open a small, 1 page PDF for example, from a local network resource). Network is 100MB, so no gigabit, but ping/throughput to the outside world is fine. Files download quickly, external sites come up instantly, the problem is only when booting up, loading the profile, and browsing intranet.
Making this more interesting is the fact that if the PCs are removed from the domain but still physically attached to network, it boots up instantly, logs in instantly, and browswing local network resources (after authenticating to them of course) is instantaneous.
There may be one more more causes, I accept that... I've combed the event log and see some group policy (errors 1501/1502) events that may indicate delay, but they don't show up every time. Also, that wouldn't explain the slow browsing of network resources.
I've done some research (read: googling) and not finding any specific incompatibilities between SBS 2003 and Win7. Could this be a kerberos issue, and if so, how would they resolve it? I believe I've demonstrated it's not a hardware issue since performance is fine if they are off domain, so it seems like it's a delay processing something on startup and then delays while accessing resources on the network that are relying on cached credentials.
I need something that can host a VPN server on Windows 7. Not LogMeIn Hamachi or the one hidden in Windows' network connections, neither of those work. I'm looking for a free program.
we have a domain network and all pcs are connected through Forefront TMG. i was able to download mail through outlook and everything worked ok. but now i get following error in my tmg "Failed to resolve server name" and outlook is not working. i am using win 7 and forefront tmg version is 7.
From a couple of days, I've the problem that SOMETIMES (not always), when I shutdown the system, appear the message concerning the system is waiting the closing of Task Host process, but I'm forced to close manually from there, because the waiting is useless.The message should be this: "1 program still needs to close: (Waiting for) Task Host Window".It happen only from 7-10 days, and Revo Uninstaller report that in last days I only install some games and these programs:
DivX Pro 6.8.0 VFW Microsoft Visual C++ 2008 Redistributable Microsft XNA Framework
Probably, all programs installed with some game.How can I do? I tried the exact version of hotfix here: http:(url) but it doesn't install because it's probably already installed (I have SP1).I want to avoid to restore an old statut with System Restore. I have Windows 7 x64 with SP1 and latest updates for everything.
I have installed the 32 bit driver for my Minolta 1300W. I can print happily in XP mode but I don't seem to be able to be able to use the printer in the Windows 7 host (64 bit Pro). Should I be able to see it as a printer if I attempt to print a document in Office? Launching the application doesn't help.
For testing i have used a one month trial version of windows 2008 R2 server.Now i need format that windows 2008 R2 version and install XP sp2 over it. when i am trying to install it , with out any boot from Cd option it is directly jumping to 2008 server OS.
On my laptop... The router signal strength bar says that i have internet access and then it says that i dont. When I try to open a webpage I get the Windows is unable to communicete with the DNS Server message.
I am currently installing a Win 7 box. When I first set things up I was able to get onto my Linux server in Network -> [server name], by logging in to Win 7 using the same user name and password set up on the Linux box.A short while later I am unable to connect - I get a dialog prompting me to enter a user name and password and a message "Logon failure: unknown user name or bad password". If I re-enter my user name and password the dialog comes back again.
I keep getting an error unable to reach server when using Nortel VPN client.The strange thing is sometimes I can connect and other times I get the above error. I have tried rebooting, even reinstalling and the problem comes and goes.
I have tried both ThunderBird and Postbox Express..But both of them cannot import my folders in hotmail..Tried many methods but it didnt wotk out too well.
Not sure if this is the correct forum, but I tried a search and didn't find a related thread. I have set up the FTP Server on two Windows 7 (Pro 64-bit) boxes via IIS. I have found that if either PC goes to the screensaver, I cannot FTP to that PC. I get "connection timed out." The second I move my mouse or hit the keyboard to get rid of the screensaver, I can immediately connect via FTP again. Neither box has the screensaver password protected. Is there some setting I need to change so that FTP can connect whether the box is logged on, logged off, or has the screensaver up? This PC will eventually serve as the main image to go out to about 300 remote sites with scripts that run overnight and will need access via FTP.
So today I started having this weird error message that my network mapped drive to the server downstairs was no longer functioning. The gist of it is that this setup has been functioning for months without hiccup or problem. The only thing that has changed is I recently converted my routers over to DD-WRT (v17990 for WNDR3400). I'm reasonably certain that this is not the issue since I can still punch in the server's IP into the network browser as \192.168.1.90 and it comes up (I can also ping it, and it shows up in the server browser for the game it hosts), but for whatever reason I can't use the server's actual machine name \mcs anymore as it gives me a connection timeout issue. So far this is what I've done:1.) Enabled NetBIOS over TCP/IP.
2.) Attempted to enable Network Discovery, but for some reason on Server 2008 R2 that option doesn't stay on, so I enabled Function Discovery Provider Host, Function Discovery Resource Publication, and SSDP Discovery in the services control panel. This caused the machine to show up in the browser, but it still can't be connected to.3.)Double checked the subnets just to be sure, they are the same.The server is attached to router 1 via ethernet. The desktop is attached to router 2 via ethernet, but the two routers connected over a wireless bridge (technically repeater bridge mode according DD-WRT).I also have a few wireless devices that are connected, but they seem relatively inconsequential. I realize this isn't really a significant problem, but its really kind of annoying
I tried to log onto Firefox and it said something about not able to connect to the proxy server. I then tried to connect to IE, Opera, and safari and they didn't work. I configured my FF settings to let the network choose the server. But for some programs, like MW2 I cannot access Multiplayer, but I can access teamspeak.
I have recently purchased a new laptop with Windows 7 Home Premium x64. I installed Office 2007, which has updated to SP3.Using XP I used to be able to successfully use Outlook 2007 for my office email, which uses a microsoft exchange server. I have not been able to get this to connect using Windows 7 despite using exactly the same settings. I have also tried a number of other combinations as advised from other sites but I can't get anything to work?This microsoft fix was also of no help... Error messages when you try to connect Outlook 2007 to Exchange Server: "The action cannot be completed" or "Your Microsoft Exchange Server is unavailable" or "Cannot start Microsoft Office Outlook".I have tried various username combinations: username or domainusername.I have tried various password security options.This is the error message I get: Outlook cannot logon. Verify you are connected to the network and are using the proper server and mailbox name. The Connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
I use the following setting:
Use Cached Exchange Mode - unchecked Encrypt data between MicroSoft Office Outlook and MicroSoft Exchange Server - checked Connect to my Exchange mailbox using HTTP - checked Proxy authentication settings: Basic Authentication
I found this error logged in event viewer and would like to know its consequences, seriousness and solution.Win Seven 64 bit laptop with original OEM applied with SP1. [code]
I just upgraded my fileserver to 2008 R2 (clean install) and also upgraded my home PC to Windows 7 (also a clean install). Both are connected together using a linksys 8-port gigabit switch and each machine has 2 NICs which are bridged. The server has a static IP and the workstation currently has a static IP as well (although I've had it set for DHCP and the problem still occurs). Network Discovery is enabled on both and they are both in the same workgroup.
Now with that being said, here's the issue.....
Periodically, the workstation no longer can "see" the server if I try to browse the network. However I can still ping the server by IP as well as name, browse fileshares and even RDP into it. The only thing that is affected is if I'm using a program on my PC and need to access files that are on a network share, then the server isn't listed under network to allow me to browse to the share.
When this happens, I can usually reboot the server and then it will show up, but there seems to be no set pattern as to when it will disappear. If both machines are left on and not rebooted, the server sometimes will just show up under Network for awhile and then disappear again. One final note, on the server, the workstation does show up when browsing the network.
Whenever I try to make a change in Internet Time Settings to the server and press either "OK" or "Update Now", I receive an error "Your changes could not be saved." I have searched for a fix but nothing I've tried has worked.
I tried updating the latest BIOS for Asus P8Z77-VLK under Bios EZ flash Utility, the CAp file is saved in a USB flash, after executint the CAP file, the computer restart and sound beeping from the computer inner speaker, screen blank, is it possible to recover it?Os = win7 64.
I have a Chinese computer that is running Windows XP professional. I upgraded to Windows 7 and all has gone well. I now have an English language computer again. The only problem I have now is it no longer can access the internet.It detects there is an internet connection but it is unable to communicate with the DNS server. How do I connect to the DNS server in order to access the internet again?
Is it possible to use Server 2008 R2, a Windows 7 workstation, or some software to collect the events logged in the Action Center on our Windows 7 clients? Also, is it possible to collect the events logged in the Reliability Monitor (View reliability history) from our Windows 7 clients.I am interested in aggregating this information in a central location i.e. on a server/workstation, which our administrators have access to. Is this possible when using System Center Configuration Manager? A smaller scale solution would be preferred as we only have around 120 clients.
i've added a fax account and can see all the sent items but none of the received ones. yet a vista client attached to the same server doesnt exhibit this problem.
I am unable to open "Computer", "Control Panel", "Devices and Printers" or any of the other options when I click on the start icon in the task bar. I receive the error message "Server execution failed" I have Windows 7 operating system.
