unable to print

have one issue on network printer, my LaserJet printer is installed in windows 2003 server and it was shared.

I’m tried to access that printer from other PC but in the same network only.

First time its works when I add that printer, by this steps :
(Add Printer -> A Network Printer, or printer attached to another computer -> Connect to this printer : \\system name\printer name -> Finished)

After restarting the system, I’m unable to access the printer, once again I have re-configure the printer. Then only I’m able to access the printer. This happens every restarting the system.

Could anyone give some solution for this issue.
