Our older client worked fine in the server and our operating system was Windows Vista. But after changing it into Windows 7, it is not working. Is this problem is happening because of changing operating system or there is any other solution?
V5R3 client may work on the Windows 7 Ultimate version. It worked on my Windows 7 Beta version so you can give it a try. I am not sure it is a operating system problem or server issue. V5R3 client should work on the V5R2 and OS/400. There is another option you can try which is better than telnet that everyone use. From Soulforge, I used TN5250. You can give it a try. Hopefully the client will work again.
