Symptoms

1. When a user tries to login to Remote Web Access from a client machine, it takes long time to evaluate user credentials. At the same time, you can observe following entries consistently in C:\Program Files\Windows Small Business Server\Logs\WebApp\RemoteAccess.log

Cause

The issue is encountered if there are any unresolved SIDs or Foreign Security Principal as member of either of these groups:

Administrators
Windows SBS Remote Web Access Users
Windows SBS Link Users
Windows SBS Admin Tools Group

↑ Back to the top

Resolution

Check all the groups mentioned in 'Cause' section, for any unresolved (orphaned) SIDs or Foreign Security Principals. For example, here are steps to check the group "Administrators":

1. Open Active Directory Users and Computers

2. Expand <DomainName>.local and click on Builtin OU

3. Go to the properties of 'Administrators' builtin group and select 'Members' tab.

4. Check all the members and verify if its unresolved SID or Foreign Security Principal. Check all member groups recursively similarly.

5. Remove the unresolved SID or Foreign Security Principal and try to login to Remote Web Access again.

Caution: You can see all Foreign Security Principals in Active Directory Users and Computers > ForeignSecurityPrincipals OU. If there is any application or service which relies on any Foreign Security Principal to be member of the groups, for example "Administrators", then removing Foreign Security Principal from "Administrators" can cause that service/application to break.
