File Channel Error for FTP reciever: Unknown Host exception

Hi Experts,

Firstly sorry for creating one more thread for this issue but I didn't find any help from previous ones.

Our file receiver channel is not able to connect to FTP server.

We are getting the error in channel monitor as " Unable to create pooled resource, unknown host exception "

However, we are able to ping this server from our network.

Also, we are able to telnet it from QPI. But not able to push messages to this server via PI.

When I try to open this ftp from browser, we need to enter the username as " Global\UserName " but it connects.

Is there any other way of configuring these type of ftp server.

I would really appreciate quick help on this.

Regards,

Vikram
