Possible Event Viewer Application Log Messages
- Could not load the cosign config file c:\path\to\cosign.dll.config
The name of the config file is probably misspelled. Either change the file name or change the value in the Registry for HKEY_LOCAL_MACHINE\SOFTWARE\University of Michigan\ITCS\Cosign\ConfigFile.
- Connection pool is busy. Perhaps the current size is too low? This value can be changed in the cosign.dll.config file.
Congratulations! You have a very popular web service! In order to improve throughput of web pages, the size of the connection pool should be increased.
