I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

See these three articles. The iana.org article seems most like it fits your situation as it refers to a local subnet, and I presume that is thatPERSVR03.pmom.local is




If you can give us more information about your environment, that would be helpful. What type of server? 2003? SBS? 2K? When is this error occurring. Anything else of interest in the Event Viewer?

We have 5 servers, and PERSVR03 is the Domain Controller, with Windows 2003 Enterprise.
The error occurs a few times a day...
With that additional information, I'd recommend the second Microsoft article I linked to above.

Windows Server 2003-based domain controllers in a parent-and-child domain environment may be unable to replicate changes

I am facing a problem in my LAN. We have a router, which has 2 network cards. From one (Card A) network card, the connection goes to the switch of one floor, and other card (Card B) is connected to the switch of the other floor. One day, we had a an issue with the Card B card. Then some of the systems under networkcard B was connected to Card A.

After changing the network card B, those system changed back to network card B. But after this, internet is getting disconnected in these systems. When I change the IP address, net gets restored. After few hours, it will get disconnected again. Can somebody help me to resolve this issue ?

Note: Card A IP: series
         Card B IP: series

would the simple removal from the domain resolve this issue at the client end or simply resetting the password at the server end to restore syncronisation with the Kerberos Ticket!
