Using FileWatcher on a Network Folder in a Service

[PeterNZ]

Hi all,

I developped an C# app which is using FileSystemWatch er. If a file is
created in a specific folder, it opens the file and does some processing.

This functionality works without problems in the following scenarios:
In a Winform App, pointing at a Local Folder
In a Winform App, pointing at a mapped network Folder
In a Winform App, pointing at a UNC network location
In a Windows Service pointing at a local Folder.

I get an System.Argument Exception in system.dll with Additional Information:
The directory name H:\... is invalid when I run the same thing as a Service
looking at a network drive (mapped or using an UNC). I use the same Network
Folder I used in the above scenarios. I doesn't make a difference if I start
it as a User Service or a Local System or anything else.

This is the FileWatcher Code:
this.fileSysWat cher = new System.IO.FileS ystemWatcher();
((System.Compon entModel.ISuppo rtInitialize)(t his.fileSysWatc her)).BeginInit ();
this.fileSysWat cher.EnableRais ingEvents = true;
this.fileSysWat cher.NotifyFilt er = ((System.IO.Not ifyFilters)
((((((((System. IO.NotifyFilter s.FileName |
System.IO.Notif yFilters.Direct oryName)
| System.IO.Notif yFilters.Attrib utes)
| System.IO.Notif yFilters.Size)
| System.IO.Notif yFilters.LastWr ite)
| System.IO.Notif yFilters.LastAc cess)
| System.IO.Notif yFilters.Creati onTime)
| System.IO.Notif yFilters.Securi ty)));
this.fileSysWat cher.Path = "H:\\MyFold er";
this.fileSysWat cher.Created += new
System.IO.FileS ystemEventHandl er(this.fileSys Watcher_Created );

Any ideas? Thank you for taking the time.

Cheers

Update: We (as in my team mate - and I was watching:-) are one step closer.
it now works with a fully qualified network UNC i.e.
//machinename.dom ain.topleveldom ain/sharename

Still no success with a mapped drive, though. But hey, I can live with the
fully qulified UNC.

Cheers
