User permissions suddenly stripped

[sazebac]

Yesterday I created a user for myself in the "users" group that I use to logon to a 2000 server domain with my laptop. I joined the domain fine, and was doing all sorts of troublshooting as that user (logging onto router, pinging, sending emails,) Today I come in and log in as this same user, and suddenly I am not able to access the internet. I'm not given a ip from the DHCP server (the router) and when I try to ipconfig release I'm told my access is denied even though I was able to do this fine yesterday. Also unable to get into TCP/IP settings in local area connection in network connections.
On the server I add this user I was using to the admin group. On the laptop I re logon to the domain but still have very few rights. My question, why was I suddenly stripped of rights and why has the change I made to the user (giving admin rights) not taken effect. Do I need to force this change? Thank you.

try a gpupdate /force

make sure your part of the Admins or Enterprise Admins group..

Thanks. Turns out the computer I was on could not get an IP from the dhcp for some reason. Once I moved to another drop things returned to normal.
But I'm having other issues.
Was trying to install Nero on a domain user's computer. Message said the user did not have permissions to install the program. So I opened that user's folder and in the "member of" tab added the admin group. Had the user log in again and still was not allowed to install Nero.
Will try the gpupdate /force command to see if that makes a difference.
