This means you will either have to invest in a third-party utility like the Quest Exchange migration tool or use a free tool from Microsoft called the InterOrg Replication tool (IORepl). As you might expect, the third-party tools are far superior to IORepl, but are als... read more.

Lately, we’ve seen a lot of activity at Gotham clients regarding increasing the functionality their SSL VPN. Gotham has installed a lot of this technology and I was thinking about the early days of SSL VPN. When SSL VPNs first came out, Gotham was one of the first movers in evangelizing what we thought was a great way to simplify access for individual users. During the education process we would eventually find ourselves in the office of whoever was running the traditional IPSEC VPN that was currently in... read more.

I recently had the opportunity to deploy Provisioning Services 6.1 to upgrade an existing client from 5.6. As there was no possibility of downtime, we decided to go with a parallel update; taking a copy of the existing vDisk and reverse-imaging it as per the Citrix documentation, and then installing the Target Device software and using XenConvert to create a new vDisk. Everything went perfectly until it actually came time to boot the target device from the vDisk. The dreaded BSOD! The 7B BSOD; which mean... read more.

Many Exchange 2010 administrators are familiar with working with database availability groups (DAG) and the multiple copies of mailbox stores they provide. One area of confusion around DAGs, however, is properly configuring DAG networks. This article reviews how to configure a multi-site DAG that consists of multiple networks. The example I will be using consists of Exchange Servers hosted in two physical locations. Each server has three network cards and resides on three different VLANs. For simplicity,... read more.

For those of you preparing to do an inter-org Exchange migration between Exchange 2010 organizations, the MRSProxy service is a required component that facilitates cross-forest mailbox moves. (Note this process is only relevant when one forest is running Exchange 2010 and the other forest has at least a single Exchange 2010 CAS Server). This service is installed by default, but is disabled. As such, it must be enabled when doing this type of migration. Microsoft published a definitive KB article on how t... read more.
