mount error(115): Operation now in progress

I'm having an issue **mounting a shared NAS drive that is hosted on a Windows 2000 server**. This is a drive that I'm certain I have access to, and I frequently access it from a Windows 7 machine and a Windows Server 2008 machine. Now, **I'm attempting to mount this drive from a RHEL7 machine**, but I'm having some issues. **What I've done:** mkdir /mnt/neededFolder mount -t cifs //DNS.forMyDrive.stuff/neededFolder /mnt/neededFolder -o username=myUserId,password=myPassword,domain=myDomain **What I expected:** I expected to be able to access the folder at */mnt/neededFolder* **What actually happened:** The error I'm receiving (partially shown in the subject line here) is mount error(115): Operation now in progress Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) **What the log says:** **dmesg** output: [1712257.661259] CIFS VFS: Error connecting to socket. Aborting operation. [1712257.662098] CIFS VFS: cifs_mount failed w/return code = -115 We can all see that there is a connection issue, that is obvious. I know both machines are connected to the network. **What can I try next to get this drive mounted?** **EDIT:** It may be worth noting that I am able to ping the DNS name and the raw IP of the remote location that I am trying to mount.
