I have a Windows7 Pro 64 bit with two shared printers attached. Both are HP LaserJet.
One of them is no longer working from other machines but one is fine.
if I browse \\computername\ I get "not enough resources are available to complete this operation" on the remote machine but it happens on more than one so I don't think the issue is with the remote machine.
If I try through add printer I get "error message 'Add printer. Connect to Printer. Windows cannot connect to the printer. Operation failed with error 0x0000007e'"
