Unable to connect to vault client, IIS / IWAM issue

[ccoleman88]

Hello,
We had some changes made to our IIS on the server which hosts our vault server this morning, since then no one is able to connect. we all recieve the same error message:

Server was unable to process request. ---> Unable to generate a temporary class (result=1).
error CS2001: Source file 'C:\WINDOWS\TEMP\-nqjhmzp.0.cs' could not be found
error CS2008: No inputs specified

The vault service is running and i can view the asmx page

When i attempt to log in to the vault admin site i recieve the following:

Login Failed: The Vault Server could not establish a connection to the database. Please check the server's log for detailed information. (FailDBConn)

sql is up and running.


Here are some IIS Details:
We have 3 web sites running, Default, SourceVault, and Sharepoint Central Administration

SourceVault website is running under DefaultAppPool That application pool identity is set to configurable, using the IWAM_<ServerName> user

When we made changes this morning, we noticed that the password field for IWAM is blank. I believe this may be the cause of the issue, but i dont know how to reset the password, we have tried, and it results in the same error. I read that this user has randomly generated passwords and perhaps that is what sql is expecting? how can i set this users password appropriately?

I have a Vault AppPool as well, however they both use IWAM user, and both experience same issue.

Any advice is appreciated.

I recently had another user who had a problem with their IWAM account. In that case what we did is set the Identity on the Vault App Pool to 'Predefined: Network Service.'

If you don't have a particular need to run the Vault App Pool under IWAM, then I'd suggest changing it to the Predefined and then have Vault use the Vault App Pool again. That way only Vault is affected by that change.

If you do need to use the IWAM account, then just let me know.

Can you tell me exactly what changes you had made to IIS?
