DOCUMENT:Q310673 06-AUG-2002 [sna] TITLE :"Cannot Open" Err Msg Opening File on Shared Folders Gateway PRODUCT :Microsoft SNA Server PROD/VER::4.0,4.0 SP1,4.0 SP2,4.0 SP3,4.0 SP4 OPER/SYS: KEYWORDS:kberrmsg kbDSupport sna4 kbsna400sp1 kbsna400sp2 kbsna400sp3 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3, 4.0 SP4 ------------------------------------------------------------------------------- SYMPTOMS ======== On a Microsoft Windows 2000-based system, you may experience errors when you attempt to open files that reside on a file share that was created by the Microsoft SNA Server Shared Folders Gateway. For example, if you use Notepad to access a text (.txt) file by using the Universal Naming Convention (UNC) as follows \\.txt you may receive the following error message: "Cannot open the \\\test.txt file. Make sure a disk is in the drive you specified." CAUSE ===== In certain situations, Windows 2000 generates a FileInternalInformation request when programs access files, and this request is then sent to the file server. The Shared Folders Gateway in Microsoft SNA Server does not support the FileInternalInformation information request type and returns an Invalid Parameter response to the client system. RESOLUTION ========== A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft SNA Server version 4.0 service pack that contains this fix.
