Alcatel Unleashed

Hi.
I try to install the 4760 on a Windows 2003 Server, but I always get the error that the LDAP port is already in use. There is no MS Exchange installed on the machine and it is no Domaincontroller.
So please help me out.

H-MAN, was Omnivista installed on this machine before??

make sure there is noe other LDAP directory app running on it as well.
