After this initial log on my xp clients lose access to network resources

What I did:
Had a mix of 98 and xp clients logging on to a NT 4.0 sp6a PDC. It was the only domain controller on the network. The server name was \\ocmntsvr1. The Domain name was ocmnt_1.

Consequently, I was going to install an Exchange 2003 server, but it need to find an Active Directory.

Therefore I did the following: Built a new NT 4.0 sp6a called \\ocmadsvr, and made it a BDC. It replicated the PDC accounts. Then I downed the PDC, promoting the BDC to the PDC. This worked great because I now had all my user account stuff.

Next I install Win 2000 as an upgrade on the new \\ocmadsvr machine. As I installed Active Directory I also needed to have a DNS so I installed it on the same machine with the following domain name: ocmsinc.org. This is our registered internet domain name.

All this seemed to work out fine. I placed the original NT 4.0 sp6a PDC back on the network and demoted it to a BDC. I had my users turn on and log in. The 98 and xp clients logged into the original ocmnt_1 domain name.

All clients log in and can use home folders and printers on the old NT machine as well as the new Win 2000 Active Directory server. However, after this initial log on my xp clients lose access to network resources on both machines \\ocmntsvr1 and \\ocmadsvr . Upon trying to gain access to a network resource what the xp clients are presented with is another log on window that says "connect to \\ServerName , user name, and password. After you type in the user name and password you get a message window that states the following: Log on unsuccessful: "The user name you typed is the same as the user name you logged in with. That user name has already been tried. A domain controller cannot be found to verify that user name

Some things I have noticed:
The xp client’s network properties showed they were members of the new domain ocmsinc.org. Also the primary DNS suffix showed the new domain name ocmsinc.org.

It seems to me a matter of inactivity. ex. not using a network resource for maybe five minutes or more.

The 98 clients are not having this problem.

Meanwhile, if anyone is wondering. Yes my xp clients do have a problem with slow log on or loading of personal settings, but these issues while the cause might be related seem to me to be two different problems. I say this because some xp client log on and load settings quickly while others are slow and some are very slow.

 

Let me make sure I have the flow and end result of your changes correct. As it stands now you have an NT4 domain controller taking the role of PDC and a 2K domain controller trying to act as BDC?

One thing is for sure - if there is a 2000 DC, it absolutely must be the PDC and running in 'mixed mode' so it will work with NT4 BDCs.

If the 2000 DC is set to function in native mode, any NT4 BDCs cease to function as any sort of domain controller. Since you mention having an Active Directory server it sounds like you set the 2000 domain controller to run native.

I have absolutely no idea what might happen if you did what it sounded like. I'd be surprised to hear that even in mixed mode a 2000 DC would allow an NT4 DC to be promoted to PDC.

You can get a little more information (but maybe nothing to help?) Here.

If I mis-read the things you did, please set me straight.
