Starting workstation?

Hi, I've had trouble with this computer picking up any shared files or
printers on the network. I read about and have found my 'computer browser'
in services to be stopped, I cannot start it as I get an error: 1068. I then
found that to enable it I have to start the 'workstation' service, but upon
starting this I get the following error:

Windows could not start the Workstation on Local Computer.

With the following both coming up in the event viewer:

1.The Workstation service terminated with service-specific error 2250 (0x8CA).


2.Details

Has anybody got any ideas of how to get the workstation started?
