I have updated this server's NIC drivers and firmware. The server in question is a HP DL585 G2 and I am using one embedded gigabit nic (the other is identical but disabled). I have also made sure that the NIC I am using is at the top of the stack in adapters and binding. The network card in the problem server is a HP NC371i.

I connected to another Windows 2003 Standard member server and did a gpupdate and then looked at the event log and it appears clean after the gpupdate command was ran. Slow link detection has not been disabled on that machine (or any on my network for that matter, with the exception of this new problem server now). ICMP is not being blocked. Windows firewall is turned off on all servers on the network (including the two DC's and this problem member server). To my knowledge there is nothing on the network limiting ICMP packet size. I certainly haven't done anything to limit it. For an update on the current status of disabling slow link detection. It has been roughly 30 minutes or so and no event log error shows after running gpupdate on the member server. When doing a gpresult everything appears to process correctly. This problem server is a new terminal server and when I logon as a TS user to this computer it still shows a 1054 error and the same 59 errors in the userenv log file. The only exception is when I login as the network admin account through remote desktops (the account I made the registry edit for GroupPolicyMinTransferRate under).

About 5 minutes ago I added that key with a value of 0 to HKLM and HKCU and when running a gpupdate I do not get the error and when looking at the userenv log I do not see the error 59 or any error that it cannot contact the DC. I do not want to say that this is it for sure but for the moment it does appear to be working. Now I suppose I should ask that since this was simply a troubleshooting step, what would I need to do in order to investigate a long-term solution to the problem? Thanks for all of the help!

When viewing the userenv log file after a reboot and after giving the gpupdate command, it shows no 59 errors and nothing shows up in the event log. Wait about 15 minutes or so and the event log shows the 1054 error and the userenv log shows the 59 error.

Also of note is that I have went so far as forcing 100Mb connection on the active NIC on the problem member server but it also did not solve the issue so I set it back to auto. The NIC in the machine is a 1Gb card. This morning I removed it from the domain and added it back. The group policy seemed to work for a bit but after about 15 minutes of tests I got the 1054 error again. Strangely if I do a gpupdate /force I don't get the 1054 error in the event log and instead get a 1704 (Security policy in the Group policy objects has been applied successfully).

You can try disabling it on the client to see if that corrects the problem by following the steps in this article for disabling slow link detection: http://support.microsoft.com/kb/910206/en-us. I would not recommend this as a long term solution but simply a troubleshooting step to see if it is indeed a problem with Slow link detection. I believe the LDAP error 59 later in the log is spurious and caused by the abortion of slow link detection. However just in case you can also validate that you can successfully make a DSGetDCName() call by using nltest /dsgetdc:<domainname> and see if it returns the same error on the machine in question? Let us know the results of each test an maybe we can provide some additional insight.

My setup contains two Windows 2003 DC's, both being DNS servers with the PDC being a WINS server. I have been working on a problem with a 1054 error in the event log for the mentioned Windows 2003 R2 x64 member server that has been added recently. Error 1054 as a refresh is the following: Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occurred. ). Group Policy processing aborted. I worked on solutions all day Friday to no avail so I am seeking assistance on this matter. No other member of the domain has this error that I am aware of. SRV records for the DC's are in the DNS and is setup correctly on the troubled member server. I have looked through WINS and saw no apparent problems with its setup either. I have updated the drivers and firmware for the network cards in the new member server and in both DC's. I will say that I have a strange issue on my local PC from time to time (and I'll assume this happens on other domain member's PC's as well) where I cannot logon to Active Directory Users and Computers by using the domain as a locator, however I am able to go into it if I selectively choose a specific DC from the list. When running netdiag on the problem member server I see no issues and when running netdiag and dcdiag on the DC's I see no issues. I am able to get to SYSVOL from the problem member server by going to \\domain\sysvol\domain<file://\\domain\sysvol\domain>. I have turned on logging of USERENV on the problem member server and I get this in the log: USERENV(37c.66c) 07:00:02:294 PingComputer: PingBufferSize set as 2048 USERENV(37c.66c) 07:00:02:294 PingComputer: Adapter speed 1000000000 bps USERENV(37c.66c) 07:00:02:294 PingComputer: First time: 2482 USERENV(37c.66c) 07:00:02:294 PingComputer: Second time: 2482 USERENV(37c.66c) 07:00:02:294 PingComputer: First and second times match.

I am very close to calling Microsoft to help resolve the issue but I thought I'd run it by you guys. I'm in the unfortunate position of being the only IT personnel here and having to be a jack of all trades as it would be. I typically have no problem solving an issue like this, especially with the help of Google but this problem just goes beyond stumping me. Any help is appreciated.
