One important consideration when you install ADMS is to think about the supportability of installing ADMS alongside other applications.
These other applications may include:-
Active Directory (aka Domain Controller)
Mail server software (Example: Exchange, Lotus Notes)
Web applications (example: Sharepoint)
Backup Software
Should a problem occur during the installation or use of ADMS, standard troubleshooting steps might typically involve uninstalling and reinstalling the components that ADMS uses (amongst others; SQL, IIS, .NET Framework, XML Parsers, WSE.). They may also involve, tweaking settings in the components or even repairing or reinstalling the operating system itself.
It's worth taking the time to think about the effects the above steps may have on business critical system such as Exchange or Sharepoint should you encounter a problem with any installed application like ADMS.
Sufficed to say, ADMS is supported for installing alongside other applications, but it is the servers administrator who has responsibility for ensuring they can get the 3rd Party applications back up and running afterwards with no dataloss.
