This article summarizes the compatibility status of GroupLogic's products on Windows 7 and Mac OS X 10.6 Snow Leopard.


AFP-based Servers: ExtremeZ-IP 7.0 or later is supported on Windows 7 for use with ArchiveConnect (see below).

SMB-based Servers: Windows 7 has not yet been certified for compatibility with ArchiveConnect, but there are no known issues. Windows 2000, 2003, 2008, XP and Vista are supported.

While most Macintosh users understand they should avoid using SMB to connect to AFP shares, there is a Finder bug in Mac OS 10.5 which may be adding to confusion and contributing to users accidentally connecting to AFP shares using SMB.

The Finder bug manifests when you expand the Sidebar's “Shared” triangle. When you navigate “Shared” the Finder attempts to connect via SMB (even if the volume is already connected via AFP). This leads users to mistakenly believe they have been disconnected and prompts them to connect using SMB.


This article explains the functions of the check_afp process (occasionally called afp_check) that runs on each Macintosh client.


Some of the the functions check_afp provides include:


BSOD STOP x50 errors when running Windows 2008. ExtremeZ-IP.exe may be referenced as the process victimized in the MEMORY.DMP file.



Update on Windows 2008 BSOD Stopx50 error.

A Microsoft hot fix addressing this issue and a knowledge base article have been published. They can be found at:


MassTransit allows you to require all web clients to select either a Forwarding Contact or a Remote Service before uploading files to the MassTransit server.

For information on how to require MassTransit 7 web clients to select either a Forwarding Contact or a Remote Service before uploading files to the MassTransit 7 server, please refer to MTWeb.


Using the "Go > Connect to Server" method to mount Volumes

The IP address and fully qualified hostname works



But using the hostname (servername) fails



If the Fully Qualified Hostname (FQHN) works but the hostname fails, the following steps can be taken to corrrect the problem.

Open System Preferences > Network

Under Search Domains, add your domain name



Instead of loading the MTWeb login page (or any other MTWeb page), I see a page with the error message "Could not get exclusive lock to application data file."

Steps to Reproduce:

Configure MTWeb normally, but do not grant write permissions to the "parsed" and "templates_c" folders. Load the MTWeb site in a browser.


After I install an Application Client or a Satellite Server why do I receive the following error when launching the application - "User name already in use. You must use a unique user name"?


By default, the Active Directory plug-in on Macintosh OS X clients (version 10.3.3 and later), will use the SMB protocol when mounting a user's network share point.

Through the use of the dsconfigad command line utility, the default protocol for mounting network share points may be changed to the Apple File Protocol (AFP).


HP moved a program that is referenced in some HP PPDs. If you are using the ExtremeZ-IP PPD download capability this is an issue if you need to support both Leopard and pre-Leopard clients with the same PPD.


Why do some Intel Macintoshes fail to reconnect to the server after a temporary loss of network connectivity?


A bug in the Macintosh OS X Finder prevents clients logging in with the Kerberos authentication mechanism from an Intel Macintosh from reconnecting to the server. Users that have temporary network connectivity issues will not automatically reconnect to the server, and instead will need to manually re-login to the server. All changed documents they had open at the time of the incident will be lost and the files may be corrupted.


Why is one client computer much slower than all the others?


The primary cause of network issues that we receive support calls about is a mismatch between the Ethernet speed and duplex negotiated by the switch and that of the Macintosh client. In some cases we find that it is actually the server that has the duplex mismatch. Either of these issues can be fixed by hard-coding the speed and duplex of the switch and Ethernet card.


Particular port configurations may allow invalid printers to be built on Mac OS X via Bonjour.


By default ExtremeZ-IP will accept inbound print jobs on port 515. This can be changed in the ExtremeZ-IP Administrator via the Print Server Settings tab in the Settings dialog box. Changing this setting can break some Bonjour printers.


When receiving forwarded files, the replacement permissions for the sender apply, not the replacement permissions for the originating user.


When a forwarded file is received that duplicates a file already in the Received mailbox, the replacement privileges of the sender of the file, not the originating user, are used to determine whether to reject the incoming file or overwrite the existing file.

activEcho: The Mac activEcho client is fully compatibile with Mac OS X 10.7.

ArchiveConnect: Users of Mac OS X 10.7 will need to upgrade to the ArchiveConnect 1.2.1 or later Mac client software for Lion compatibility.


If ExtremeZ-IP encounters a crash, sometimes the best source of information is retrieved from a Dr. Watson Log. Dr. Watson gathers stack information and obtains symbols from ExtremeZ-IP to aid in figuring out where the crash occured.

For Dr. Watson to work, it must be "installed" as the default application debugger. Upon reboot this information can be lost and when a crash does occur Dr. Watson may not catch the crash. This document will explain how to configure Windows so Dr. Watson is allways installed on startup.


MassTransit may report error messages when sending certain files to WAM!NET Address Book contacts. These files may contain illegal characters that are valid on Macintosh or Windows platforms.


WAM!NET has its own rules for valid filenames. When sending or receiving files via WAM!NET that have not followed WAM!Net rules, the files will not be transferred. Please check the WAM!NET user manual for complete information. To make certain that all files are successfully transferred, please follow these rules regarding file naming:

There are two registry tweaks specific to Windows 2003 servers which will improve performance under certain conditions. These changes are recommended for our customers who have:

  • A large number of files shared out.
  • Folders containing a lot of items (browsing large folders).
  • A lot of users or if the server is under heavy load.
  • Background processes that monitor the file system for changes such as Windows Search.


What is mobilEcho?

mobilEcho is the industry’s first and only Mobile File Management (MFM) software for enterprise iPad users. mobilEcho enables enterprise IT to provide secure access to enterprise file servers for iPad users, eliminating the need for work-arounds like emailing files to yourself or storing critical enterprise files in unsecure third-party cloud providers.

On Windows

First back up your database as follows

Once the backup is complete:


Illegal file/folder names and conventions for the following operating systems:
Mac OS 9
Mac OS X



In the realm of cross-platform file sharing, sometimes the end users are not aware of the limitations posed by the operating system. This article will explain which characters can cause problems with files that use these characters.


This article applies to:

  • Acronis Access Connect (formerly ExtremeZ-IP)


Will Choose IP Printer work in Mac OS X Classic Mode?


No. Choose IP Printer is not supported in Mac OS X Classic Mode. In order to use Choose IP Printer, the Mac client must be booted into Mac OS 9.

Group Logic recommends using the built-in Chooser and printing using AppleTalk to the Acronis Access Connect IP Print Server from within Mac OS X Classic Mode.

mobilEcho clients connect to mobilEcho servers on port 443 by default.

If the mobilEcho server that contains your home directory shared volume(s) is configured to use a port other than 443, you will need to create a Network reshare path mapping that points to the correct mobilEcho server and share on the correct port. This will allow the mobilEcho client to know to connect to the server on the non-default port.


How can I move the activEcho FileStore to a non-default location?




In our example we will use a FileStore running on the default port of 5787 located at “C:\Program Files (x86)\Group Logic\activEcho Server\FileStore” and we will be changing it to be located at “E:\activEcho Data\FileStore” but keep the port the same.


mobilEcho accepts SSL user identity certificates for authentication with an HTTPS Reverse Proxy server. When using reverse proxy for access, if you have enabled certificate authentication as your login method, the mobilEcho client app will be automatically challenged for a user identity certificate when it attempts to use the proxy server to access a mobilEcho server. In order for authentication to take place, an SSL user identity certificate must be added to the mobilEcho client app.
