Hi,I have a workflow which calls an external task for deployment. The external task in turn calls an ipl file. When I execute the workflow, the workflow runs smoothly but as soon as the external task is reached,the workflow gets stuck.The error as logged in the iwutild.log is " Impersonation error " for a user with some argcount and errorcode 1317.I have tried making the changes in the iw.cfg but still the error persists.The Teamsite version is 6.7.1 SP1Any pointers on the same would be highly appreciated.Regards,Meghna
