I have never heard of ReplacePrefServ.exe.
I think that may be a file made by a third-party.
What configuration changes do you need to make? I would imagine that these are changes you can make within the product.
In the past you had to do custom scripting to use preferred servers throughout LANDesk but with the later version you have actions like map to preferred servers in provisioning which resolved these issues for many tasks.
With these I have no more custom scripts so hopefully you can find ways to complete what you need within the product now as Dave mentioned.
In fact i think the ReplacePrefServ.exe was built on Prefmap.exe.
I'm using Map to preferred actions in provisionning, but i also need to change the name of the server to the name of the preferred server in some configuration.
In 9.5 it was working very well, since i've upgrade in SP2, there's a "NULL" character at the end of the preferred server name so it makes some trouble when replaced in my configuration files;
Ther's perhaps other solution, but i haven't find any when i search.
Any idea are appreciate.
I'll try to decompress and made changes in the ReplacePrefServ.exe
In final i've change the code and générate a new Exe.
It's working fine.
