Error INVALID_WRPC_TOKEN


I was wondering for some time to identify the cause for the error “INVALID_WRPC_TOKEN ” as it fills all the event viewer log file.This issue appears to be introduced after CRM ROllup 7 as MS added some security changes.

Just found this, which fixed a colleague’s issue with CRM Rollup 7. The main point in the article is that the donwload.aspx page doesn’t work in Rollup 7 and you get the trace error:
Message: INVALID_WRPC_TOKEN: Validate WRPC Token:WRPCTokenState=Invalid, TOKEN_EXPIRY=4320, IGNORE_TOKEN=False, TOKEN_KEY=blah blah, ErrorCode: -2140991221″

The fix is to turn off token checks by creating a registry key, with the value 1:
HKLM\SOFTWARE\Microsoft\MSCRM\IgnoreTokenCheck (DWORD)
