Dell Optiplex GX270 - Outlook would not launch - froze before giving the user a logon screen. Reinstalling Office 2003 & repairing Office 2003 did not solve the issue.
Trying to delete the user's profile froze the mail control panel.
Trying to add a new profile produced this message:
The time limit for logging on was reached while waiting for system resources. Try again.
Clicking OK on the message produced another error message code 0X8004xxxx (I didn't write it down)
I went to the properties of the Intel Pro/1000 MT network card & clicked on Configure. On the Advanced tab, I set the Speed & Duplex property to 100Mb Full & clicked OK. The network connection status changed from "connected" to "disabled" and the control panel froze.
I restarted the machine & logged on as a different user. I could add profiles & logon to Outlook.
Had the user log back on & everything works fine now.
