unable to convert files to pdf in network drives

Hi Team

Iam using adobe acrobat pro 11 in windows7 64 bit OS.When ever iam trying to convert files from text or word to .pdf iam getting the errro message in devices and printers.

one thing i observed that when i choose local drive eg:c:drive iam there is no problem.but when i given network drives path then its getting error.i have full permissions on network drive and also i can able to save any files,able create files, folders in network drives, So there is no permission issues.

Could you please provide the solution to fix it.

Thanks in advance

Regards

Siva
