Windows Server 2003 and about a dozen XP and Win7 machines.
One machine, FDRight, is a Print server for a Brother laser printer.
Another, FDLeft, is also a PS for an identical Brother printer.
Printing is distributed over the two print servers.
Two machines, PHRight and Treat, lost printing to FDR.
Other machines pointed to FDRight print OK, as does FDRight itself.
Was able to set up to print to FDLeft, so immediate problem of not being able to print is solved. but a remaining more serious issues remains.
In attempting to add the printer on FDRight to PHRight and Treat, with Add Printer, could not. Message said Print Spooler not running and to restart it or restart the print server. Checked Print Spoolers on PHRight and Treat and FDRight. All were Started, but I restarted anyway.Made no difference. So restarted all three machines, again, no better.
Then began experimenting. to see what could and could not be done on other machines. On a machine, EX1, that is printing fine to FDLeft, tried to Add Printer on FDRight. Could not, access to resource denied. Then created a shared folder on FDRight with access by Everyone. Could not even access the shared folder from EX1.
Any suggestions of where to look for next step will be most appreciated.
The only thing I thought of to do that I did not do was to restart the central server. I didn't want to disrupt ongoing work on all the workstations, and nothing seemed to be pointing to the server as an issue. I did check the Print Spooler on the Server. It was running, but I restarted it anyway.
