I have a windows xp, computer that is connected to server through workgroup environment. after log in it gave me an error unable to connect to server. when i click ok on the error it goes away but i can ping and access the server from that computer and there is no connectivity problem. sever is running DHCP services only and it register that computer correctly. Dont know why i am getting the error after boot up. If i i log off and log back in it dont give me that error. just does that when booting it up.
