Please do not flame me to bad, I am very new at this and I am surprised I got this far.
I am using v3.4.06, my host is 1and1 using MS SQL. I have setup two different databases, one is named 728 (for indianaharleyforum.com) and the other 743 (for duramax-lbz.com). I have 2 domains, duramax-lbz.com and indianaharleyforum.com.
I set the Config.ASP file to strDBType = "sqlserver" in both setups. I set the strConnString = "Provider=SQLOLEDB;Data Source=mssql07.1and1.com;database=db223990743;uid=xxxxxxx;pwd=xxxxx;"for the Duramax forum. I set the strConnString = "Provider=SQLOLEDB;Data Source=mssql07.1and1.com;database=db223990728;uid=xxxxxxx;pwd=xxxxx;"for the Indy Harley forum. The files for each site are in different directories and the databases are setup as they should be.
My problem is that when I change the forum name for one site the other site gets changes too. The home and forum URL info and Title info is changed too.
I did a fresh install of the Harley forum. I deleted all the database files and all of the web files before the new install. It still happens every time.
If I need to provide some other information let me know.
At first I couldn't get back into to Forum when I changed the config. (yes I ran Setup on both) I had to reset the one I changed back to the standard config, run setup, then change cookies to web. Then I chnaged the config back to your suggestion, ran setup, and everything worked fine.
