First you have to load HFSS on both machine. The username and password with administrator privelage must be the same on Server and Client machine. This will allow both machine to communicate to each other. Here's the important step, on your client machine find your ansoft installed directory. Default should be C:\Program Files\Ansoft. Right click on Ansoft folder and enable sharing. Select "Share this folder", leave it the share name default. Now click on permissions tab. Another window should pop up. Click on the Add tab, another window should pop-up. If your working on the server machine, you should scroll down and look for your client machine user. If your working on the client machine, scroll down and look for your server user. Once you locate the user click add. Now should be back to the previous pop up windows. The server or client user should be added to the "Share Permissions" windows. Under Permissions, Check "Full Control, Change, and Read" box. Click OK, you should be back to original pop up window. On the top, there should be 3 tab option, General, Sharing, which you shoulb on, and Security. Now select Security tab. Now follow the same step as instructed above. Add user on the server and client computer. Allow "Full Control" to the user for your Server and Client computer. Click Ok to all the windows until you get back original windows explorer. Now follow the DCOM instructions and REBOOT. This is very important when you make changes to your DCOM setting. Good Luck.
