Question : Problem: Upgraded RAM from 512MB to 1GB and now I can not defrag

I just upgraded the RAM for one of my employees personal machines and when he tries to run a defrag on the memory he gets this error:  Access denied: C\winnt\system32\dfrg.msc.

He is running Windows XP Pro and it is a Gateway E4100
