When attempting to use an OU, domain, AD site to enumerate objects within an InTrust site, computer accounts are missing.
This occurs because InTrust by default excludes machines that have out of date passwords (according to the DC InTrust uses) when using the 'Computer list from Domain Controller' on the Domain Enumeration tab on the site.
1. Right-click on the site that is missing computers and choose Properties
2. Click on the Domain Enumeration tab and make sure the 'Computer list from Domain Controller'
3. Uncheck the 'Ignore computers for which the password has not changed for more than' option
4. Select OK, click the blue check mark to commit changes and then try to enumerate the site again
This affects all versions of InTrust (not InTrust for Events or InTrust Express) but the option to enumerate sites manually (for verification purposes) was introduced with InTrust 9.0
