Dragnet No Longer Works with Name Change of Vault Repository

I had Vault and Dragnet both setup and working perfectly, then my boss decided that the name of my Vault Repository wasn't quite right. So we changed that, and while Vault still works, Dragnet is now failing to work. We get the following message when going to the Dragnet url:

Server Error in '/Dragnet' Application.

What are the results from this query:

SELECT name, login FROM sgdragnet.dbo.users WHERE uid = 1

Alright, this is really weird. Its working in IE, but not FireFox. Before the change in the vault repository it was working in FireFox with no problem. But now it works fine in IE and has the runtime error note below in FireFox. I don't think I've ever seen an asp.net app with that had a runtime error in only one type of browser!

OK, I knew that sounded too weird. I removed the cookies for FireFox for my Vault/Dragnet site and everything works now. I still don't see why something in a cookie, presumably about the repository name, would cause a runtime error though. Anyhow, I'm sorry to have wasted your time.

I have no idea why that would have happened. I'll log an investigatory request to see if it is something related to a cached cookie.

Thanks
