I have come in this morning after not a good monday to find all hell breaking loose!
My log on scripts dont work is the main one, we have had a new photocopier with account tracking, the nice people at konica came and set it up, however since this my logon script is causing a error (please see attached) also looks like the conflicker virus has come back as people cannot get to the server and some can? am i right in thinking the conflicker virus is a DoS attack? does anyone have a definate way to get rid of it? have e-mailed and rang symantec but they tell me tp consult the website... useless.

Only way to really erradicate would be to re-ghost I'd say if it keeps coming back. You don't want that flying around your network.

In the short run, download KKiller (a Kaspersky tool) to kill off conficker on each workstation. Funnily enough, it's much better than Kaspersky AV itself. I run it as a scheduled task on my Windows servers and use it to disinfect workstations.

HTH, good luck.
(Another thing I meant to say: download Microsoft Security Essentials and schedule updates with this tool if you're not using WSUS:
Long-winded but works better than the commercial AV imo.)

As far as I understand it MSE is for home use only, not schools. So be careful where you use it.

Looks like you're trying to unmap a drive which isn't currently mapped.

The other thing to do is to make sure your login scripts run with cscript (rather than wscript which is what you are using)
the benefit of this is that error messages etc are not done in message boxes (which confuse users and need "OK" clicking) but just written to the console (where users will ignore them but everything will just work :-))

There are lots of conficker threads on this site already- worth your time checking.
We got hit with it Jan '09- took down everything e.g. because of its constant attacks on the administrator account eventually everyone's accounts got disabled automatically by the AD.
Besides all of the problems it causes the single all-conquering best thing to do is to update your images and implement a mass reimaging plan. We had our staff told that the internet would be out of use for a couple of weeks, ofc this is in the most dire of situations.
If you can catch it in isolated areas- then disconnect those machines, sort them out while windows updating all the non-infected. This whole experience has caused me to use WSUS much more regularly!
We haven't had a take down of any sorts for over a year now Good luck.
