I have windows 2000 server with about 10 windows xp clients.

It has been working great for the last couple of years.

All of a sudden some users cannot print. If user try to print, he gets
error " printer cannot be found" or sometime "printer is not available on
the server "

Sometimes it works ok but all of a sudden it disconnect the printer from the
client. It happens with any users and other users are able to print.

I have checked DNS and it seems to be working fine.

I would really appreciate if you kindly help me.

Thanks
