Error while deploying from NWDS

Hi,

i am getting the following error while trying to deploy a PAR file from NWDS through export.

PAR upload failed:C:\Documents and settings\Trials\Trials.par

Please check the userid and password.

i cross checked the userid and password.both are correct. the same par file is deployed successfully in other servers.

this error occurs only for PAR file deployment. other applications like webdynpro and all are deploying successfully.please help.

/* useful inputs will be rewarded*/
