Blue Screen Bother (Citrix shadow)

I’m having a problem.

Sometimes, not that often, but often enough, when I’m shadowing a user in Citrix it blue screens the server.

The stop code is :0x0000000a
(Oxb3835f93, 0x0000001c, 0x00000000, 0x80118dca)
IRQ_NOT_LESS_OR_EQUAL.

I think it may be device driver related. Nothing new has been installed recently and it’s starting to bug me.

Has anyone else encountered this whilst shadowing and what can be done about it?

Cheers,

Steve.
