Describe the bug

I'm trying to configure a UNC path for the Stdout log.

<httpPlatform
		stdoutLogEnabled="true"
		stdoutLogFile="\\SERVER\path\stdout.log"
		startupTimeLimit="20"
		processPath="C:\Program Files\nodejs\node.exe"
		arguments=".\serv.cjs"
>

No log appears, but a warning in the eventlog with a strange prefix before the path (see below at exceptions).

Expected Behavior

A file named (or starting with the name) "stdout.log" should be created in the specified directory when the server starts.

Steps To Reproduce

Put a UNC path as value of the stdoutLogFile attribute of the httpPlatform tag in the web.config file.

Exceptions (if any)

In the Eventlog I find a warning

Could not create stdoutLogFile \?\UNC\SERVER\path\stdout.log_20250122131757_2184.log, ErrorCode = '0x800700a1'.

HttpPlatformHandler Version

v2.0 RC3 (httpplatformhandlermodule_x64_en_v2_8.0.3.msi)

Anything else?

node-v20.18.0-x64

Thanks for the report. It seems to be an issue from the original ASP.NET Core module code, so I opened an issue there for Microsoft to investigate.

Once they resolve it, the patch will be merged here too.
