I am having a strange problem. I am running 10 XP Pro clients in a Windows 2000 Small Business Server environment. I have one PC that seems like it is loosing its secure relationship with the domain. It is fine on start up, but after a period of hours, it claims that the network drive names are already in use when you try to access a mapped drive. If you map manually, it prompts you for a login to the domian server. Why would it drop me? I think that I have DNS problems, because it does take a while to log on. I dont know if that has anything to do with this issue or not. How would I find the IP of my DNS Server? We are using static IPs. Thanks in advance for the help!
