We get more and more reports that it is not possible to start the administration inside ADMS Console 2014.
This can occur for a number of reasons.
#1 caused by a defect, fixed in DL22258964
#2 The issue occurs when the AutodeskDMPool is stopped.
To solve this open IIS Manager and to to Application Pools:
If you still encounter the problem when AutodeskDMPool is started or it is not possible to start the AutodeskDMPool please log a support request.
Another scenario where this can happen is if there is a permssion issue for the impersonation account over the database files. In some circumstances having insufficient privileges over the mdf and ldf files can result in this when starting the ADMS Console. Most commonly this happens if the mdf and ldf files were attached using SQL Management Studio, detaching via SMSS and reattaching the KVM and other DB's via the ADMS Console should resolve this.
Another Scenario Solution.
When clicking the filestore on an enabled Vault (local or remote) in the ADMS Console. See TS1094948 for the permissions required over the filestore.
