this machine is disabled for file encryption

This is not anonymous 'admin' - this is global, build-in domain administrator, who have all privileges and which is used for domain maintenance, install/remove apps, copy files, etc. We provide users to Endpoint Encryption via Endpoint Users module and this users are assign from our Active Directory service. We can't add the individual accounts for each administrator to each machine, because we have blocked possibility of logon local users. Huh, ok sorry but I again don't understand your reply. But when we have only one (EEPC v6.2.0.296, EPO v4.6.2) this issue also occured. We have different version of EEPC from 6 to 7 (I recently upgrade epo to 4.6.6, eepc to 7.0.2 and other extensions and package to latest versions). However issue still repeat on various PC.

After this operation finished, new password form popped and I entered always the same password, which mentioned above. I can repair this issue only with a Endpoint Recovery console, enter Challenge Code and reset Token. This issue is strange because when 'Password entry disabled.' warn appears on 1 PC I can login on the same credentials in other computers. We use only one identical password (never changed and never expires) for Administrator user (both in EE and AD service). Our problem is that above message appears sometimes to times when we wan't login within preboot authentification. We add this account recursively from domain admins OU from Active Directory to all encrypted computers. We have about 150 PC in our company an use one universal Administrator account for management (domain admin). I'm new geek on this forum and I have very strange issue with Endpoint Encryption password synchronization.
