writing files

[Shaun Wilde]

What sort of permissions do I need for an ASP.NET application to write a
file to a network drive/create folders etc? i.e. via \\mymachine\sharedrive\
or a mapped drive

Thankx

Shaun

By default the ASPNET user account does not have access to network
directories. Either grant it access or have ASP.NET run under a different
user account by using impersonation.

For example, you can add a line similar to this to your web.config file:
<identity impersonate="true" userName="domain\MyAppUser">
password="password"/>

Here's more info on impersonation:

Hi Shaun,

Thanks for your post!

I think "Steve C. Orr [MVP, MCSD]" has provided you a valid useful solution
for this issue.

The reason for this issue is that Asp.net defaultly runs in a build-in
account named "Aspnet", which is a local machine-specific account. It can
not be authenticated by another machine on the network(because there is
also an "Aspnet" account with different password on that machine, and there
is no Authority to vouch for the account).

Actually, this issue is such a frequently asked question that microsoft has
released a KB for this issue, please refer to:
"You receive a "logon failure: unknown user name or bad" error message
while accessing remote security-enhanced resources from an ASP.NET
application"
http://support.microsoft.com/?id=842789

In the KB, Microsoft has provided us 6 options to resolve this issue, for
your information.
