I have 650 POS Windows XP machines accessible via a VPN connection to our data center. These machines are scheduled to reboot via scheduled task nightly between 2 and 3 AM - There are 3 different times within this hour that all of these machines reboot. SO - when a reboot occurs theoretically, there are about 200+ machines rebooting at once.
We are seeing hit and miss issues of extremely long logins occurring (5-10-15+ min). I have enabled the verbose logging for the login process - and we are seeing that the machines are hanging on "Applying Group Policy" or "Applying Schedule Tasks" or "Login Scripts".
My thought is - GPO over VPN may impact the performance, and in addition, I could have 230 machines trying to pull down GPO settings at the same time - it may cause enough network congestion to cause a slow link.
So my question is - how can I determine if the GPO is detecting a slow link? If I need to adjust the default of 500kbps, how do I determine where to adjust that number to? I realize that a simple solution to this MAY be to further stagger the reboot process, however, I only have the hour window for this type of maintenace because of our hours of business / other automated processes that occur during the night.
Thanks in advance for any replies!
