Directory.Exists(@"\MyServer\Images") command works correctly while Directory.Exists(@"\MyServer") doesn't.

Can you suggest me a "Directory.Exists" equivalent to check the accessibility of servers.

Please don't suggest to ping the server, because sometimes ICMP is blocked by server firewall and the PING command doesn't work. And don't refer to the similar questions where using the PING command can be acceptable by question posters.

How do you plan to access the server? If you want to access an UNC path, check whether this path is accessible. If you want to communicate over TCP, check whether you can establish the connection on the port. – Thorsten Dittmar Mar 10 '14 at 10:07

Tim, the link you suggested above offers using the PING command that I can't use as I said in my question. – Murat Korkmaz Mar 10 '14 at 10:09
Why do you repeat the question? – Thorsten Dittmar Mar 10 '14 at 10:10
Thorsten, because the author of the "duplicate" question might be satisfied with using the PING command while I am not. – Murat Korkmaz Mar 10 '14 at 10:12

Well, you could clarify your question as to *how* you want to access the server. Then we could maybe provide better answers. – Thorsten Dittmar Mar 10 '14 at 10:16
@Murat: it seems to be the best option. Apart from that it shows also different ways. It's a duplicate question anyway. – Tim Schmelter Mar 10 '14 at 10:45
