mount error: cifs filesystem not supported by the system

While working with CentOS Linux 5 & Kernel Version 2.6.18-8.1.6.e15 I was trying to mount a CIFS type filesystem.

The issue originally began when I "unmounted" the mount. After that, I could no longer "mount" it back.

The following is used to mount:
mount -t cifs //servername/fileshare /mnt/net -o user=username,pass=secret
The following is the response:

mount error: cifs filesystem not supported by the system
Refer to the mount.cifs(8) manual page ( mount.cifs)
Someone mentioned to check for the module with the following code:
ls -al /lib/modules/`uname -r`/kernel/fs/cifs
total 256
drwxr-xr-x  2 root root 4096 Jun 18 12:47 .
drwxr-xr-x 27 root root 4096 Jun 18 12:47 ..
-rwxr--r--  1 root root 249124 Jun 14 2007 cifs.ko
Seems like it is there.

It was mounted fine only a couple days ago, and nothing has changed besides me "unmounting" the mount. Now it says it is no longer supported.

Help is most appreciated.

Check if the cifs module is loaded.

Thanks for the reply Jschiwal, but I am very new to Linux.
Can you please explain how to load the module.

Thanks, I really appreciate your help!
