Those algorithms, however have been superceeded by CTCP in Windows Vista/2008 (and 2003/XP64 with hotfixes). With all those points in mind, calculating the optimal RWIN value is a bit more involved than just plugging any number in the Windows Registry. Below is a good way to accomplish this in 3 steps: 1.
Windows 95 had a "hidden" default for MTU set in the registry at 1500. This was appropriate for LAN's and all Ethernet connections, but can be very inefficient when using a PPP dialup connection. This has now been recognized by Microsoft and was corrected in Windows 98 to some extent. Inspired by the script of Charles_1.0 I created a function that uses the .Net ping class to find the biggest transmission unit size. It is simple and fast. Just open Powershell, run the script and type Find-MTU
Oct 25, 2010 · I've installed another Windows 2003 Server with Exchange 2007 Hub Transport Role, which has the 1 Cert with just SMTP as the service. We're experiencing the exact same issue. At this stage i don't see any changes made specifically on the Checkpoints regarding the MTU. I'm still looking into that. On the ASAs the MTU is specified to 1500.

Hi, Can you give me a list of issues one may encounter if a Windows Server 2012 R2 network has an MTU incorrectly set to 9000 (Jumbo) and the underlying network only supports 1500?

C:\Windows\system32> Note that my MTU sizes on my LAN and Wireless cards are 1300, because the Cisco VPN client is installed, and I believe it sets them low to avoid PMTU issues. This command does not work in Windows XP or Windows Server 2003 as it complains that RRAS is not running (I suspect it would work if RRAS *was* running).-Eric Not eligible for Windows XP and Windows Vista users.)
