Can't encrypt files in vista ultimate Sp1

[Guest Sax]

when I try to encrypt any file/folder, the properties window gets busy for a

minute then it gives me the following error message " Access Denied. You will

need to provide administrator permission to change these attributes" with 2

buttons continue and cancel, press either of them doesn't solve my problem

and encrypt the files/folders I want.

well am new to windows vista, just installed it like 2 weeks ago and been

having this problem since then, I installed it myself so my account supposed

to be on admin level.

 

PS. when I enabled the built-in administrator account on welcome screen and

logged to it I tried to encrypt a random file and it worked smoothly not sure

whats wrong with the other account any hints, advice is much appreciated

 

Thanks in Advance
