I'm having this issue using both the 32 and 64 bit RepositoryAccess 9.0.0.0 libraries. This has been running fine for over a year, until just this last week. I believe it started after we applied updates to our Windows Server 2008 R2 server.

I'm running the following code snippet

static void Main(string[] args)
{
	Session session = new Session();
	session.LogIn(new RepositoryRegistration("server", "repository"));

	DocumentInfo doc = Document.GetDocumentInfo(177876, session);

	FolderInfo folder = Folder.GetFolderInfo(177885, session);

	doc.MoveTo(folder, "Successful Test", EntryNameOption.AutoRename);
}

If the destination folder is named, e.g. "Destination Folder", this will work fine. However, if it's named "1.Destination Folder", I get an "Invalid Request" exception.

Does anyone have any ideas as to why this is happening, or steps I could take to fix it? Thank you.

Edit

Upon further testing, it looks like it's the period that's causing the issue. I can rename our folders to work around this, but I'm still scratching my head as to why the issue popped up out of nowhere.
