I've tried that before and a lot of the time it just fails. One of the things to take into account here is that standard domain users can't play about with many things in Control Panel including the Services option. I'm not prepared to give it to them either because as anyone who maintains a domain will tell you, users play about with things, mess them up and then claim that a) they didn't do anything or b) they shouldn't have the option to do it if it can cause damage...etc.
Anyway, I appreciate the suggestions but maybe its just some incompatibility thing.
I'll now list everything I can think of which will help taking into account that they didn't work (and its pretty big!):
1. Uninstalled all related software, rebooted the machine and started again.
2. Totally wiped a computer, reinstalled everything with same results.
3. Tried leaving the printer off shared i.e. not accessible from the network.
4. Updated to the latest drivers.
5. Made the user a local admin of the computer and installed the software as them.
6. Upgraded to the latest service pack.
7. Ran numerous error checkers, defraggers, anti-virus etc
(By the way, these aren't in any particular order)
There is a lot more, I just can't think of it right now. A lot of things I've thought 'this isn't going to work' or 'theres no reason this should work' (which none of them have), but I'm open to any suggestions no matter how stupid they sound.
This isn't a major problem...its just irritating when you get the same people calling each week and asking where their printer has gone. Then theres the usual banter about 'every IT solution is to reboot your computer' which is wearing a bit thin....
I've rambled on a bit, and its late so I'm going to bed. If anyone has a solution it would be most appreciated...
