Archive data with MP277 in a shared folder

Hi,

I have a MP277 touch 10''. I need to archive data in a shared folder on a PC Server. The panel is conected to an ethernet network. I think that the network configuration on MP277 is correct (IP address, subnet mask, gateway and DNS) because in the command prompt on MP277 with the command "ping" I get reply from the PC Server, I use ping command with the PC names. (you can see this on ping.jpg).

In the PC Sever I've created a share folder with name "prueba" and I give all permiss to the same user that I configure on the Network ID on the MP277. From another PC,using this user andthe same IP address configured, I connect to the shared folder on the PC Server whithout problems. But if I try to connect to PC Sever from MP277 I get the message that path is incorrect. (you can see this on error.jpg). If the runtime starts in the diagnostics buffer I get the error number 80015 "the system cannot find the drive especified".

I've got connect MP277 to a shared folder whitout problems but only using direct crossed wire between MP277 and the PC Server.

Do you have any idea?

Thank you for your help and I am sorry for my english.
