Step 1 - Check the local security settings

Go to Start -> All Programs -> Administrative Tools -> Domain Controller Security Policy.(On client machines go to Control Panel -> Administrative Tools -> Security Policy and select 'User Rights Assignment').

Expand the 'Local Policies' group and select 'User Rights Assignment'.

• Make sure that the user identity is allowed to 'Access this computer from the network'.  If 'Everyone' or 'Administrators' is in this field that is sufficient.
• Make sure that the user identity is not included in the list of users under 'Deny access to this computer from the network.  If 'Everyone', 'Administrators' or any other group that the user identity is associated with is in this field %PRODUCT_NAME% may encounter problems.
• Make sure that the user identity is included in the 'Allow log on locally' field.  If 'Everyone' or 'Administrators' is in this field that is sufficient.
• Make sure that the user identity is not included in the list of users under 'Deny logon locally'.  If 'Everyone', 'Administrators' or any other group that the user identity is associated with is in this field%PRODUCT_NAME% may encounter problems.

Step 2 - Check third party security software

Some third party firewalls or intrusion detection systems may prevent certain users from accessing the machine locally or through a network.  We suggest suspending these services temporarily in order to isolate the problem.  If a problem is found with third party software you may need to adjust it's settings to allow %PRODUCT_NAME% the permissions that it needs to run.
