I have created several COM automation servers which are installed on a Windows 2000 server. I can call the servers from my applications no problem and they work fine on local Data. However, when i ask the servers to work on data on another machine it all goes horribly wrong. The data is on a mapped drive on another Server. I was using the local drive mapping on the automation server to point to the tables i require but no luck. I have also tried using the UNC path to get to the remote data but it still goes tits-up. The share on the remote server is set for 'everyone' (temporarily!) in case its an authentication problem but still no luck. As the COM servers work fine on local data, i can only think its a authentication problem....anybody any ideas?
