Had the pleasure of clustering SSIS the other day and it was not as simple as a thought it should have been. Not that it was difficult it was just being tricky. To cluster a service like this you have to select the Generic Service resource type for the cluster resource. When I looked at the service name of SSIS I went to services.msc to find that service. On the General tab you can see the "Path to executable:" There the service executable name was listed as msdtssrvr. After putting that name into the Generic Service Parameters it gave me an error that this was not the name. After some digging on the file system I found that the actual name is MsDtsServer. Apparently the letter e was left out of the original entry I had. One other area that needs some attention is the Registry Replication page, here you must enter SOFTWARE\Microsoft\Microsoft SQL Server\100\SSIS\ServiceConfigFile.
Hopefully that helps you.
Back in February I needed a script to display the groups a user belonged too. Today I was asked about the opposite. I needed to find a way to list the members of a group. Thankfully I blogged about the first issue in February because that led me to the solution. I'm actually using the same DSGET command but instead of using the user command I'm using the group command.
DSGET GROUP CN=West_Coast_Sales,OU=Sales,OU=GROUPS,DC=adminprep,DC=com -MEMBERS –EXPAND
Hopefully this solution works for you too.
