Altiris Agent caused PCs to not boot.
Last week I had a problem whereby we moved our datacentre from one building to another. The next day a few PCs decided they would not boot.
If I unplugged the network cable and logged on as local admin they booted OK, but when the cable was plugged in they would just hang after putting in the username and password.
I re-imaged one and it worked fine. My colleague found that uninstalling the altiris agents (symantec management agent 7.1 sp2) solved the problem.
I am going to try reinstalling the agent s today.
Anyone else come across anything similar?
