I don't think I understand what the problem is?
You're saying writing to UNC is fine, while log4net complains about T: being
unavailable? As Steve says, this indicates that T: isn't mapped for the logged
on user (did the login script run successfully?)
Re your code below: If T: and the UNC path both points to the same folder for
the logged on user, why would you (or log4net) want to translate T: to its
equivalent UNC path?
Have you tried writing directly to "T:\" from your service? (from outside
log4net)
I don't think you'll see usage of WMI in core log4net. I haven't tried this
myself, but I believe you can override RollingFileAppender's File {get; set; }
if you want to implement the code you posted.
Best wishes,
Dag

Subject: RE: Problems with Network Drive
Steve,
I am aware that mapped drives are only visible to the current user. Our Windows
service is started using a specific user account and our VB.NET application is
able to cope with reading in configuration files (including the log4net.xml
file itself) from a UNC or mapped drive using the following bit of code:
Private Sub New(ByVal configFile As String)
'check that the config file is mapped drive
ConfigurationFileDetails = configFile
If Not configFile.StartsWith("\\") Then
'convert mapped drive letter
Dim search As New Management.ManagementObjectSearcher("SELECT RemoteName FROM
win32_NetworkConnection WHERE LocalName = """ + configFile.Substring(0, 2) +
"""")
Dim remoteName As String
Dim mgmtObjCollection As Management.ManagementObjectCollection = search.Get()
For Each mgmtObj As Management.ManagementObject In mgmtObjCollection
remoteName = mgmtObj("RemoteName").ToString
If Not IsNothing(remoteName) Then
remoteName += configFile.Substring(2)
ConfigurationFileDetails = remoteName
End If
Next
End If
I was hoping that there might be something similar in log4net itself?
