OCS Save Password

If your machine isn’t connected to a domain and you would like to save your password in OCS to eliminate logging on every time, add the following registry key.

For 32bit Windows OS

HKEY_LOCAL_MACHINE\SOFTWARE\Polices\Microsoft\Communicator  

REG-DWORD SavePassword=1

For 64bit Windows OS

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Polices\Microsoft\Communicator 

REG-DWORD SavePassword=1

In reading a few blog post I found that:

Please make sure you don’t install the “MS09-056: Vulnerabilities in CryptoAPI could allow spoofing”  KB974571 until this problem has been fixed.

MS09-056: Vulnerabilities in CryptoAPI could allow spoofing:

Known issues that affect this security update

Services that are required by Communications Server are not started after you install this update and then restart a computer that is running any of the following versions of Communications Server:

• Live Communications Server 2005 (LCS)
• Live Communications Server 2005 SP1
• Office Communications Server 2007 Enterprise edition (OCS)
• Office Communications Server 2007 Standard edition
• Office Communications Server 2007 R2 Enterprise edition
• Office Communications Server 2007 R2 Standard edition
• Office Communicator 2007 Evaluation version only*
• Office Communicator 2007 R2 Evaluation version only*

When this problem occurs, the required services behave as if an expired trial version of the product is installed. This behavior affects the whole Communications Server enterprise that is hosted by the affected server or servers.

Microsoft is investigating this issue, and will determine the most appropriate way to address it. Customers who are not running OCS or LCS server are not affected by this known issue, and can safely ignore this issue.

Customers who have deployed the OCS or LCS product on a server should assess the risk that is involved to decide whether to install the security update on that server. These customers should revisit this Knowledge Base article often, because this article will be updated as soon as more information and a resolution are available.
