This event also seems to be related to name resolution problems. A good idea is to check wether WINS and DNS are set up and working properly. Also, ensure that all servers use the right DNS and WINS servers.
Another reason could be improper time syncrhonization. I know from experience that when time is not properly synchronized, a lot things can go wrong. This is always on top of my troubleshooting list. I know (seen in one of my other threads), that this specific problem can be related to timsync. So be sure to check.
I've also posted yet another possible reason on this in another thread, which can be found at
