Access windows symbolic link from linux cifs

I have created symbolic link of the mapped drive (DOS share) on Windows 7 computer 200.90.12.25. The symbolic link was created using mklink command. Trying to access this from Linux (Raspberry PI) using CIFS command, I get mount error(5): Input/output error. CIFS command and dmesg attached below. I cannot access the DOS share from Linux because of NETBEUI. Line diagram shown below for reference. **CIFS command** sudo mount -t cifs -o user=username,guest,vers=2.0 //200.90.12.25/DOSA /home/pi/myNAS/myShare **dmesg** (also on the Linux client) [1027098.510573] FS-Cache: Duplicate cookie detected [1027098.510583] FS-Cache: O-cookie c=c6d9fc6c [p=33027f2d fl=222 nc=2 na=1] [1027098.510588] FS-Cache: O-cookie d=e8ce4e52 n=203d934d [1027098.510592] FS-Cache: O-key= '020001bd0a090c12' [1027098.510606] FS-Cache: N-cookie c=435e27ec [p=33027f2d fl=2 nc=0 na=1] [1027098.510611] FS-Cache: N-cookie d=e8ce4e52 n=9f19c9a0 [1027098.510614] FS-Cache: N-key= '020001bd0a090c12' [1027098.515854] CIFS VFS: cifs_mount failed w/return code = -5 As per the suggested comments, i have tried below commands. I got the same mount error(5): Input/output error sudo mount -t cifs -o username=username,guest,vers=2.1,mfsymlinks //200.90.12.25/DOSA /home/pi/myNAS/myShare mount.cifs sudo mount.cifs //200.90.12.25/DOSA /home/pi/myNAS/myShare -o username=username,guest,domain=domain,mfsymlinks any alternative solution much appreciated.
