DirectAccess IPv6 Support for WorkSite and iManage Work

DirectAccess IPv6 Support for WorkSite and iManage WorkiManage Work (formerly WorkSite) is a popular document management system commonly used in the legal, accounting, and financial services industries. Historically, there have been issues getting WorkSite to function over DirectAccess, because WorkSite used IPv4 addresses and DirectAccess clients use IPv6. When a DirectAccess client is outside of the office, it communicates with the DirectAccess server using IPv6 exclusively, so applications that make calls directly to IPv4 addresses won’t work.

One way DirectAccess administrators could make WorkSite function was to use portproxy to create v4tov6 address and port mappings on the client. However, this method is error prone, difficult to troubleshoot and support, and doesn’t scale effectively.

The good news is that beginning with release 9, the iManage Work client application has been upgraded to support IPv6. However, it is not enabled by default. To enable IPv6 support for iManage Work, add the following registry key on the client side (not the server!). No other changes are required.

HKLM\Software\Wow6432Node\Interwoven\WorkSite\Server Common\

Type: REG_SZ
String: IP Address Family
Value: IPv6

You can also use the following PowerShell command to add this registry entry.

New-Item -Path “HKLM:\Software\Wow6432Node\Interwoven\WorkSite\Server Common\” -Force
New-ItemProperty -Path “HKLM:\Software\Wow6432Node\Interwoven\WorkSite\Server Common\”-Name “IP Address Family” -PropertyType String -Value IPv6 -Force

After validation testing is complete, deploy the registry setting via Active Directory group policy preferences to all DirectAccess clients and iManage Work will function perfectly over DirectAccess!

DirectAccess Client and Server Settings GPOs Deleted

Microsoft Windows Server Active DirectoryFor DirectAccess deployments where domain controllers are running Windows Server 2003 or Windows Server 2003 R2 using the File Replication Service (FRS) for replication, DirectAccess client and server settings Group Policy Objects (GPOs) may be deleted. If these GPOs are deleted, DirectAccess connectivity will be disrupted. If the GPOs cannot be recovered via backup, it will be necessary to rebuild the entire DirectAccess deployment from scratch.

Microsoft recently updated their DirectAccess Unsupported Configurations documentation to reflect new guidance for DirectAccess deployments where the FRS is used for the distribution of Active Directory GPOs. DirectAccess is no longer supported in environments where FRS is used for SYSVOL replication.

What this means is that if you plan to deploy DirectAccess, domain controllers must be running Windows Server 2008 or later, and Distributed File System Replication (DFS-R) must be used for replication.
