How to Disable SSL 2.0 in IIS 7 (and 7.5)

Disabling SSL 2.0 in IIS is a critical requirement to pass PCI Certification. I have no idea why IIS 7 ships with it still enabled, perhaps for super old browsers? We should only use stronger SSL 3.0 or TLS 1.0.

Here’s how to disable it in IIS 7 and IIS 7.5 Continue reading “How to Disable SSL 2.0 in IIS 7 (and 7.5)”

Controling Compatibility View in IE

After hours of frustration trying to make some CSS look right for a selection of people using IE8 I gave up.

There has to be a better solution.

Internet Explorer 8 and Internet Explorer 9 include a Compatibility View feature that displays websites that were created for older browsers as they were designed to appear with Internet Explorer 7. You can enable Compatibility View in Internet Explorer, most users don’t even know they are in Compatibility View  – which is where the problems arise!

Active Directory DHCP Authorisation Issues

So you just deleted a DHCP server in your Active Directory site and can’t authorise a new one? Yeah… Stupid.

A client of mine recently deleted a Windows Server running DHCP and couldn’t authorise the new server of the same name.

[Snippet] Forcing Replication Between Domain Controllers

…because some people still don’t know!

  1. Open Active Directory Sites and Services.
  2. In the console tree, expand Sites, and then expand the site to which you want to force replication from the updated server.
  3. Expand the Servers container to display the list of servers that are currently configured for that site.
  4. Expand the server objects and click their NTDS Settings objects to display their connection objects in the details pane. Find a server that has a connection object from the server on which you made the updates.
  5. Click NTDS Settings below the server object. In the details pane, right-click the connection object whose From Server is the domain controller that has the updates that you want to replicate, and then click Replicate Now.
  6. When the Replicate Now message box appears, review the information, and then click OK.

That is all!

Exchange 2003, 2007 & 2010 Topology discovery failed, error 0x80040a02 (DSC_E_NO_SUITABLE_CDC)

A client has been struggling with Exchange 2003 for some time now and I’ve got the project to roll out Exchange 2010. The first hurdle I come to is a new incarnation of a pre-existing problem from Exchange 2003 – simply put “Can’t find a domain controller”. Which means it can’t mount the Information Store. Brill.
