Trying to install the Remote Agent through our domain I ended up with 16
pc's that it would not install on. They gave the following error:

Error creating object on \\machinename\administrator

I searched the knowledge base and got three answers
One says a prior uninstall of Remote Agent was not finished because the
machine was not rebooted.
(didn't apply to me but rebooted anyway - same error)
Another solution says to turn off Windows XP Firewall
(XP Firewall is not enabled)
The final solution says to disable Force Guest Login by unchecking Use
Simple File Sharing and rebooting.
(that has no effect - same error)
