I moved to another switch and I still get the same issue and I can't go any further with drivers. I suppose the step I need to take now is to purchase a new NIC. Since everyone has strong feelings for Intel I wanted to ask what you guys suggest. This is a HP DL585 G2 server (rackmount) with PCI-X slots.

The only way I was able to correct it was to switch the primary IP address to another NIC in the server what was connected but not configured. It was an interesting exercise at the time since I couldn't get to the console. In my experience, that kind of DNS response is indicative of packet corruption of some sort.

I'm certainly nowhere close to an advisor on this so if one of you more familiar could help me out on deciphering the code on a couple of things. Are the following two items normal (they didn't look right to me): 1) DNS: Question Section: _ldap._tcp.Default-First-Site-Name._sites.dc._msdcs.DOMAIN. of type Unknown Type on class Unknown Class DNS: 0x32E3:Std Qry Resp. for [EMAIL PROTECTED] 2) DNS: Question Section: _ldap._tcp.Default-First-Site-Name._sites.dc._msdcs.domain. of type Unknown Type on class Unknown Class DNS: 0xB4E5:Std Qry Resp. for . of type Unknown Type on class Unknown Class You may need more information so if I can get you anything else let me know. These entries just seem out of place to me, especially the one that has been displayed as "[EMAIL PROTECTED]" Donavon -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darren Mar-Elia Sent: Monday, January 15, 2007 4:08 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] 1054 Error (Windows cannot contact DC - Group Policy) The other thing that would probably be worthwhile is to do a sniffer trace from this server during the GP processing cycle. That may point out some network issues that are not coming out of the userenv log. Darren -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darren Mar-Elia Sent: Monday, January 15, 2007 12:50 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] 1054 Error (Windows cannot contact DC - Group Policy) Sorry, just catching up here. In terms of updating the driver, if it's a MS provided driver, I think it would say it in the Driver Details. You might want to run Windows Update and see if there are any optional updates for that NIC driver--if MS provided it originally they may have a Windows Update way of getting it. In terms of disabling slow link for all users, that's a toughie, because that key is in HKEY_CURRENT_USER, which means a user has to be logged on to deliver it, but its also in the policies key, which is permissioned away from regular users by default. If you can get GP to process at least once when the user logs on, then you can deliver it using the User Configuration GP setting. However, if per-user GP processing is not working, its kinda of a chicken-and-egg thing. The not-so-fun way of doing this would be to temporarily make all users logging into that MS a member of the local Administrators group, and then deliver the slow link disabling registry entry via logon script. But, that is not ideal of course.

I'm not sure I can believe that HP would put a defective card in such a machine. You'd think others would have the same issues in mass quantity if that were the case. I'm also using Broadcoms in other HP servers here (including the two DCs) and they have not had any issues. It is all too easy to chalk up a problem like this to network cards, but I don't think it explains why the GPO is applied successfully without issues within the first 15 minutes or so after a reboot. There are no other problems cropping up from these Broadcoms either. Now for a question, how do I disable slow link detection for all terminal service users on this problem server since that seems to have fixed the issue? I need to make the change in the registry on the problem server apparently as making the switch in the GPO itself seems to not have any effect.
