start process in web site folder from asp.net V2

I posted the question on how to do this last week and got it to work at
home just fine. Now on my machine at work, I can't get it to work
anymore. I've checked the permissions on the web site root folder and
it has script & execute permissions. I also checked to make sure the
anonymous user had execute permissions. I'm not sure what else to do.
The error I get when I try to fire off a process is The filename,
directory name, or volume label syntax is incorrect. I can take the
whole filename with arguments and all into a cmd prompt and it runs
fine, so I'm sure it's a permissions thing. I'm just not sure where
else to look. Anyone have any ideas? Thanks.

BTW, I've tried impersonation also and that isn't working either. I've
checked what the User.Identity is and it's mine, not the ASPNET
identity. But, from what I've read, any process that is started in an
asp page is run under the ASPNET identity. I've tried doing the
microsoft ASP.Net 2 impersonation which is supposed to let you assume
the logged on user identity instead of ASPNET, but I still get the same
error. Any ideas would be much appreciated! Thanks.
