Install went smoothly, I installed everything according to description and got no errors whatsoever during install.. all checkpoints were marked done/installed and also the SMF package installed without any trouble.
direct access to SMF forum without or with administrator account also works but when using the mambo bridge in wrapped/unwrapped mode it just fails with the two different situations as described in my first post.
the forum is located in a subdirectory of the mambo installation (root directory of my website). I'm using the CB login module, but I don't think that's the problem cause the forum fails even when logged out.
Maybe it's the windows environment in which the website resides?
Win2003 server + IIS + PHP + MySql (+additionale requirements for mambo). Mambo itself works like a charm.
I'm currently researching the problem but I hope some more similar cases will report on the forum so it can be resolved quicker

If I find the cause or solution I will post it here.. otherwise I will be checking this forum regularly to check if someone got it fixed
