Scheduling C# app throughts Webclient exception -

i have developed c# application download zip file site, when manually run app, job , exits, when schedule run automatically using task scheduler in windows, throws web client exception error. please me regarding this

the part of code downloading file is

webclient wc = new webclient();                 wc.downloadfile(<site>, "feed.zip"); system.diagnostics.processstartinfo pinfo = new system.diagnostics.processstartinfo("extract.bat"); system.diagnostics.process process = new process(); pinfo.createnowindow = true; pinfo.workingdirectory = directory.getcurrentdirectory(); process.startinfo = pinfo; process.start(); process.waitforexit(); 

the batch file extracts zip file.

i see these possible problems:

• if run application directory.getcurrentdirectory() result in different path. directory.getcurrentdirectory() set bin-folder, in production environment, can point every, depending how process executed (for example: if create shortcut on desktop, can modify start in-folder.
• if current directory configured wrong, application not able find extract.bat.
• while debugging have rights on outputfolder. when application executed batch process, runs under different account. account have rights write output folder?
• the website accessing might require valid account. possibly have valid account. account application running in production, might not valid account website.
• you possibly behind proxy. perhaps need configure settings getting past proxy. in account, these settings configured inside internet explorer. perhaps production account not have these settings configured.
