Exception message: Invalid license. PidGen.dll cannot be loaded from this path C:\Program Files\Microsoft Dynamics CRM\Server\bin\PidGen.dll
This server and the install of MS CRM has been up and running for over 3 years and never showed sign of this error until after rollup 21.
This error effected all deployments on each server and halted the application use completely, bringing production use to a halt. The issue occurs randomly but generally once every 24 hours. After roughly two weeks the issue appears on another server that we applied rollup 21 too. Same issue and result, which occurred randomly once every 24 hours.
To work around the issue, a simple recycle of the MS CRM app pool returns the application back to a functional state until the error appears again. We have reached out to MS directly but they have so far been unable to identify the root cause or reason for the error.
1. Our licenses are up to date and valid.
2. Our group policies have not changed as other MS CRM servers we host do not exhibit the issue.
3. We have tried replacing the PidGen.dll from another known good server, but the issue continues.
4. We have granted all rights/access to the MS CRM related folders and IIS related folders, but the issue continues.
5. We bounced, restarted and validated all system services are up and functional.
6. We have eliminated the anti-virus.
If anyone has any insight or ideas on this please post. We are at the point of rolling back to update 10 or worse, migrating all deployments to a new clean server install.
Cheers!
