not able to access share folder on Windows Server 2008

[guest]

Subject:
=====
We are not able to access share folder on Windows Server 2008 server even if
we are using administrator privilege with proper permission. The built-in
Administrator account will not have such problem.

Cause:
=====
a result of Admin approval mode (AAM) for User Account Control(UAC).

Admin Approval Mode (AAM) is a UAC configuration in which a split user
access token is created for an administrator. When an administrator logs on
to a Windows Server 2008-based computer, the administrator is assigned two
separate access tokens. Without AAM, an administrator account receives only
one access token, which grants that administrator access to all Windows
resources.

With UAC turned on, we will get access denied message when connecting to
network shares. This is expected behavior.

Resolution:
======
Turn off UAC on the Windows Server 2008 machine:
1. On the Windows Server 2008 machine, click Start, select Control Panel.
2. Double click User Accounts.
3. Click "Turn User Account Control On or Off" link.
4. Deselect "Use User Account Control(UAC) to help protect your computer".
5. Click OK and restart your computer.
