Thanks for all your suggestions.. I shall try them all and see where it takes me.. Regards Rose Rose,=20 You're right, this is real weird . .=20 When was the last time the troublesome citrix servers were rebooted?=20 Try setting up another share somewhere, give 'everyone' full share / full ntfs rights to the files therein. Log onto the problem server as a user and attempt to access /run the files.=20 Try changing the .cmd to .bat.=20 Have you set any auditing on the problem citrix servers? Load user manager on the server, go to 'computer' - 'select domain', and type in the name of the server you are on. From here you can set a local machine audit policy for logon /logoff events, and permissions issues.=20 You can also look at utilities like 'filemon' and 'regmon' to see if there's a hidden permission in the registry of system files on the TS servers which is stopping users from browsing to and executing a batch file.=20 Good luck J _________________________________________________________________ Add photos to your e-mail with MSN 8.
