I have WinXP Pro connected via ADSL. Just over the last couple of days whenever I run Windows Update and press "scan" it states that its looking for updates and then hangs. The IE window running Update hogs the screen and I have to kill the application using WinXP CTL-Alt-Del.
Office update works OK as does all other internet access.
Also, what is really strange is that if I connect using a dial up modem it seems to work OK.
I had this problem once before on a different system and it seemed to be fixed when I set the MTU values to 1458 in the registry. This hasn't worked this time.
I have tried various fixes found on the web and nothing seems to work.
