Cool, glad it's working again.
One thing you might do though....if it's been awhile since you ran any virus or malware scans, you might want to run those. It may be nothing, but I searched that other dmserveresl name you gave, with the "e" in it this time, and one of the links told about a possible trojan that renamed the dmserver.dll file to dmserveresl.dll as it's backup. If you *do* have that on your machine, it may rename that file again, so it would be a good idea to run some scans just to make sure something else isn't lurking on your hard drive that *may* have changed that in the first place. Glad the problem was found though!
