Accessing files Problem

[Guest NoelBorg]

I have a server with windows server 2003 and other pcs are connected through

a domain with the server. I had to format one of the pcs and installed win xp

prof again. The problem is this when the user logs in with the password that

he had he cant create/delete folder in ( example program files ) because

error access dnied is given. I have checked the other pcs and found out that

when a user logs in on another computer that he usually dont use the same

thing happens.

Note:When an administrator password is used everything can be accessed but

when a different account is used on another computer that a person dont use

the access denied msg appears.

Can someone help me out with this please.
