If company upgraded the network and firewalls and i have to test connectivity for each server we use (database, reports, file, etc.. the client is windows 2000 and XP and servers are mostly UNIX and one is windows.

Would you use SSH to test login to unix server and whether servers can talk to each other?

Do i  need putty or windows has some SSH client built in.

    Windows has no SSH client, use Putty and make sure that firewalls are open for port 22.

    is this the only thing you check after a netowrk upgrade. just SSH conection to port 22.

    For just testing server connectivity, you can use ssh but if you want to test database, fileshare, printing etc between clients and servers, you need to do more of course. Your firewall(s) will have logging that will show issues (blocked). Your previous firewall(s) will have a set of rules that you can learn from (or import them into the new fw).

    first you need to check with ping with servers ip address if servers are reachable then try using putty to connect to server. Also, test if thats working before they make any changes so that you will know if there is something wrong with there changes. have a test plan before and after migration.
