We have various vista machines on our network (mixed lan/wireless). Over the last two weeks a problem has developed on all of them. The printer - a toshiba 281 colour photocopier is connected via lan and has its own printserver (as standard). It also has a network smb server used as a data sotrage device for scanned images and saved faxes. Over the last two weeks all the vista machines have developed problems communicating with the toshiba device. One still prints, but cannot access the smb - message comes up saying device won't accept connections from that particular pc. On the other machines, the printer driver won't work - print folder comes up with "printing error". These machines also can't access the smb space. (Same error message)
None of the xp machines or servers are affected.
Bizarrely, when the vista machines which won't print are restarted, the items left in the print queue print out between logging in the profile and the machine completing loading the desktop. To me this suggested a firewall problem, or some software interferring with the print communication, but I can't trace anything.
Reinstalling print driver - installation can detect but can't access printer - installation fails.
Tried installation manually poiting to ip address or device name on network ie \\tosh-281 - but same error reply.
Tried disabling firewall
Tried disabling antivirus
Check for changes on lan/wireless router - no changes over past two weeks.
Tried installing as administrator and through admin profile and using safe mode - no effect.
Run out of ideas after eight hours on this and now reaching for a large mallett. Any help would be much appreciated.
