Hi all,
We've currently got a single print server running 2003 R2 with all of our printers on, the printers are deployed via GPO, though on some machines, often certain machines, but generally random, the printer won't be added...
Sometimes you can just go to the Directory and add the printers and they will be fine, but most of the time it'll start adding and come up with "Windows cannot add this printer, The Specified Port is Unknown" - usually the user has to do a restart and sometimes the printer will come back, other times they'll have to use a different machine to even print...
It does it to all sorts of printers - Kyoceras, Canons, HPs, Epsons, it doesn't seem to be just one printer which makes me think it's not a driver issue, however I'm not going to rule it out...
Any help would be amazing!
Thanks,
Ruan
