Re: Works perfectly on my desktop, timesout on the web server.

Sorry, I do not have any other information I can provide here.
We generally do not recommend WinSCP .NET assembly for this kind of use:

Works perfectly on my desktop, timesout on the web server.

Greetings

In our attempts to resolve the issue with writing to a sessions log, we have tried various approaches from the forum:

1 Running the process under a different account. 
processInfo.StartInfo.Domain = "DOMAIN"
processInfo.StartInfo.UserName = "username"
processInfo.StartInfo.Password = securePwd

2. Running the executable under a different account: 
session.ExecutableProcessUserName = "DOMAIN\username2"
session.ExecutableProcessPassword = securePwd2

And combinations of the two with not success. We are using impersonate in our web.config because it is required.

Any suggestions or insights you can provide, would greatly appreciated.

Works perfectly on my desktop, timesout on the web server.

When through suggested the link provided.

session.DebugLogLevel = 2
session.XmlLogPath = "D:\inetpub\wwwroot\AppName\log\sessionXML.txt" - I have given the appPool, all the relative AD groups hate write permissions to the folder. Same issue. Yes, I am using impersonate.
session.DebugLogPath = "D:\folder\folder\debug.log" This works

Is there a session setting missing for the server or a setting in IIS?
Thanks

I have tried giving my personal account, app pool and my ad group read/write and even full control to the root folder which the log folder is a child of.
What am I missing?
