I have made a fresh installation of opmanager and it seems quite impossible to add nodes. I keep getting the following error: Entries for the device are either partially added or removed.Click [here...] to remove and readd the device

I have a ms sql database and have tried to follow the tips in http://support.opmanager.com/AddSolution.sd?solID=1808 but that doesn´t seem to work for me.

Stefan
