Service currently not available!

[dXh]

Hello. I am trying to set up roundcube on IIS.  Have installed twice following the install directions.
Everything seems to install fine, I get no warnings or errors.  
Once the install is complete and I go to use roundcube for the first time I get the following error:

SERVICE CURRENTLY NOT AVAILABLE!

Error No. [0x01F4]

I have verified the db name and user credentials.  They all are good,  I can connect to MySQL using the same info.

Any suggestions would be great.

Cheers

David

Update:
Fixed this by updating the php.ini file to point to another port
