Aarrgh, patched a W2K8 server to SP2 and the spooler service has gone nuts; near as I can tell it's constantly trying to run an installer named hpzbdi32.msi over and over. I can obviously delete the dang thing but that won't stop it from trying to run it over and over. Anyone ever run into this and solve it easily, i.e., not uninstalling/reinstalling a driver user by 300+ printers? gracias. Thankfully I cloned the thing before putting on SP2 and it's a holiday so I can hack and slash at will.
