Hi, all,I installed vista on my computer several weeks ago and joined the domain of our company. So, I have a domain account (eg. user.domain ) on the computer. Now after I let the computer leave the domain, I can not login with the domain account. Before leaving the domain I set a new account as administrator, but now after logging in with the new account, I can not do any change to the computer. And the worst thing is I can not access any data under the domain account, say, c:\users\user.domain\ .... . Every time when I try to modify the computer setting, User Control is promoted and ask me for the administrator password, but there is no place to input the password and the 'OK' button is disabled. Does anyone meet similar problem?Thanks in advanceFeng

Hi, can you disable UAC by the following methods? Method 1: ========== 1. Open User Accounts. To do this, click Start, type msconfig in the Start Search box, and then click msconfig.exe in the Programs list. If you are prompted for an administrator password or for confirmation, type the password, or click Continue. 2. On the Tools tab, click Disable UAC, and then click Launch. 3. Close the Command Prompt window, and then restart the computer. Method 2: ========== 1. Click Start, go to Control Panel. 2. Double click User Accounts. 3. Click Turn User Account Control on or off. 4. Uncheck the box and click OK. Let's see if you can perform the above steps. If you receive the message when performing the steps or the message still occurs, please let me know.
