Win 7 64x Hangs on login -waiting for group policy
Weird one this.
Our new IT room is causing a few last minute headaches, so much so I went in today to try and tackle the issues head on but to no avail.
It is a windows 7 64x only domain, with server 2008r2.
On logging in, approx 10 out of 34 machines take an age, waiting for the group policy service. These 10 are no different in terms of machine, build, ou group or software. They go through 3 separate switches each with a different link back to a central network switch.
I have tried quite a few things - and sometimes I can get the whole room to login in 13 seconds. Other times, most do bar this 10. These 10 dont change, but they do sometimes work, and this happens nowhere else in the school.If I move the machines elsewhere they work, if I swap their cables in the switch with a working one, they still wont work.
Any ideas?? I have checked the error log. Not a lot there that is relevant - but perhaps Im not looking for the right thing. One thing I did notice today - when doing a GPUpdate today, most did it, including some of the 10 not working, but a few others told me they could not apply policies because they could not verify the location (the exact error message alludes me at this time)
I was thinking it was down to switches, but 2 are brand new HPs,and it doesnt happen to all the machines on one switch...
Im fresh out of ideas, it is as random as it sounds.
