We’d want to see what the contents are of “C:\ProgramData\Thinkbox\Deadline10\deadline.ini” here. The main line is going to be the one starting with “NetworkRoot=” as that’s what the Monitor is trying to load.
For the original error, we’ve been collecting various cases over here:
Problem solved with Edwin’s help on phone support. So I have no idea why, but during installation, the deadline.ini file in the c:\program data folder was being set to read only , and because of this, could not write the critical line “NetworkRoot=C:\DeadlineRepository10”
Once I was able to write this line in the file everything works as normal.
Found this thread after going through something similar; the Slave crashed while rendering and after that it stopped connecting to the repository and was giving the same error.
In my case I had to do something else. The path was set correctly on the "“NetworkRoot=” but the database was configured to use a SSL certificate which path wasn’t set (gone after the crash maybe?). Manually setting the certificate path solved the issue.
