Hello ,

Occasionally my PC - Windows XP Professional will not boot correctly. I get to the windows desktop but cannot run any programs. I've enabled boot logging and note the following as the last entry when this occurs:

Did not load driver \SystemRoot\System32\DRIVERS\ipnat.sys

To be fair I can see some other entries also state 'Did not load...' including the file below extracted from a good boot!

Running Windows XP with an ASUS P5 WiFi motherboard, 2G RAM, 250G Sata Hardrive

A reboot will normally resolve the issue and all is then well. When this failure occurs the system time can be seen to be frozen.

Any help would be gratefully received. Thought to be virus/spyware free. Combination of paid for Spyware Doctor and Avast Antivirus freeware.
