Can't access network printers on NT Domain from XP Workstation

I have a large network with NT 4.0 servers.  We have over 30 shared HP Laserjet printers running on several NT 4.0 print servers.  Everything works fine with our NT 4.0 and Win2k workstations.  Just upgraded a couple of W2k systems to XP Pro and we can't seem to get them to use the shared network printers.   Each box has several shared printers showing up in the "Printers and Faxes" window.  Each of them says "Unable to connect" under the Status column.  The local printers show up just fine and but can't use the network printers.  When I try to click on one of them I get the following message "Operation could not be completed.  Print spooler service is not running".  If I try to add a new network printer I can browse and see all the shared network printers on my domain.  When I select one of them and click "Next", I get the following  "Windows cannot connect to the printer.  Either the printer name was typed incorrectly, or the specified printer has lost it's network connection.  For more information, click Help."  If I try to open one of these printers, I get the following message "Operation could not be completed.  The driver that you are trying to install is not compatable with Windows XP."  It seems to me that because all the printer drivers on my NT 4.0 print servers are NT 4.0 or less that I need to get newer drivers on the print servers.  Is this possible?  The current drivers seem to work fine on my W2K workstations.    Any other suggestions.  I really need to be able to print to the network printers from these two XP workstations.  Thanks!
