We have quite a few workers who use Citrix to work from home.

Now one of them suddenly cannot log-on - they get the username & password screen and key in their details ok - the system has a think then kicks them off with no error message

I tried myself to log in as that user with same result - tried deleting their profile and recreating it but made no difference.

Event log does show 2 errors relating to them - one says "Event 1000 - Windows cannot query for the list of Group Policy objects" and then "Event 1000 - Windows cannot connect to XXX.Local with (0x0)"

Anyone got any thoughts here?

Is it just one user?

It sounds like a DNS error, but why it is only affecting one user is a bit strange. When you get this error, can you ping XXX.local from that machine? Or is it the Citrix Server itself which can't contact XXX.local?

I had something similar with a 3G stick. It was trying to DNS outside of the 3G router and XXX wouldn't resolve, but XXX.local did.

It is just the 1 user - all the others are fine.

It is the Citrix Server that is giving the "cannot contact xxx.local" error message when that 1 user tries to connect.

A couple of ideas:

* Can you try renaming their profile and getting them to log on again
* Have a look in terminal services manager on the server and see if they have any sessions running, if so, kill em
