Disk Management does not load on Win XP

I'm trying to change a drive letter and while trying to enter the "Disk
Management" I'm getting this error:
"the service did not respond to the start or control request in a timely
fashion"

I've also tried to run the "logical disk manager administrative service"
service directly but i received this error:
"Error 1053: The service did not respond to the start or control request in
a timely fashion"

There is a Microsoft solution that didn't worked for me

The error logs from the Event viewer are attached here:

I'll appreciate any idea you may have about resolving this problem and if
there is another way to change drive letters without using Disk Management,
I'll be happy to hear about.
