IWP - Can't enable: Port Conflict

[panchristo]

I am trying to enable IWP sharing on my laptop to test my database for IWP on the same machine, but I continuously get the same error: "Filemaker cannot share files over the network because of a port conflict... bla bla", and no matter what address I enter, I get the same error.

I've read some similar posts but nothing really helped. I also disabled my firewall but still no progress.

I ahve run the same file at work on Windows XP and opening the database concurrently in FMP and Mozilla works fine.

Could it be that my laptop runs on Vista Home Basic and such services are probably limited?

If yes, is there any way to bypass it (e.g. settings in registry)?

Set the FM preferences to use another PORT for IWP. Typically use 591.

No Luck with this port either
