Hello,<BR><BR>I have a web service that was kicking off an executable. All was working fine until I upgraded to Windows XP. Now, the process doesn&#039;t start and I don&#039;t get any exceptions. The same code runs fine from a Windows form...I have no idea what it is. I have tried mucking with security. Anyone also have this problem or know what might be going on? If there is anymore info I need to provide, let me know.<BR><BR>Thanks in advance,<BR>Danny
