DCOM Error

Toshiba Satellite Pro, L300EZ1004X, Win XP Pro, SP3. Two years old, original

OS. Not a downgrade from Vista, 3 GB RAM, hard drive 85% free.

Recently upgraded to SP3. Beforehand I checked the Toshiba download site

for any new drivers for this model and downloaded and installed a new Intel

PRO/Wireless 3945ABG adapter driver I’ve been getting the following Error

in Event Viewer since the driver upgrade. I rolled back to the original

driver, but still receive this error.

Further, I can't find the exact key referred to in the Microsoft suggested

User Action

I am out of ideas where to look next. Anyone have a suggestion. I did a

Search for all changes made on March 28 when I first received the Error

message. This is the date I made the Intel driver change.
