Disable and Remove Half-Open TCP Connections Limit (to Unlimited) in Windows 7 and Vista SP2 with EnableConnectionRateLimitin Registry Key
Officially, the incomplete half-open outbound TCP connection attempts allowed at any one time is now unlimited by default in Windows Server 2008 and Vista SP2 (Service Pack 2), and Windows 7. Actually, the ability to limit or restrict number of half-open outgoing TCP connections system can create or establish is built into Windows Vista SP2 and Windows 7, however its disabled by default.

11.5.2006 Changes to TCP/IP in Windows Vista
Unless you've been living under a rock, you no doubt know by now that Microsoft is currently working toward releasing the next version of the Windows operating system, Windows Vista. As you would probably expect, Windows Vista will be loaded with new features. One thing that caught me by surprise though was that Microsoft has made some major changes to the way that TCP/IP is implemented.

23.11.2005 Next Generation TCP/IP Stack in Windows Vista
Microsoft Windows Vista Beta 1 and Windows Server "Longhorn" Beta 1 include a new implementation of the TCP/IP protocol suite known as the Next Generation TCP/IP stack. The TCP/IP protocol stack provided with Windows XP and Windows Server 2003 was originally designed in the early 1990s and was modified and enhanced over time to meet the needs of home and enterprise users. The Next Generation TCP/IP stack in Windows Vista and Windows Server "Longhorn" is a complete redesign of TCP/IP functionality for both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) that meets the connectivity and performance needs of today's varied networking environments and technologies.

09.12.2008Fast TCP acellerates Web
Network congestion, like
vehicular traffic jams, is
getting worse. No matter how
fat the pipe, the antiquated
Transmission Control Protocol
(TCP) never fully utilizes the
available bandwidth.
Developers have tried for
several years to improve TCP
performance and its Layer 4
counterpart, the User Datagram
Protocol, using revised
protocols and hardware
accelerators. Members of the
Internet Engineering Task
Force have promoted
experimental TCP alternatives.
None have gained wide
acceptance. Likewise, silicon
vendors have devised in-line
accelerators, collectively
known as TCP Offload Engines,
or TOEs, but the standalone
TOE chip is being replaced by
a TOE accelerator block that
resides in an Ethernet switch
or network processor.
Another solution would be
to redesign TCP to take
advantage of smart network
routers, but that would make
obsolete existing hardware and
require users at both ends of
a data transmission to buy new
equipment.
Now
http://www.fastsoft.com/>FastS
oft Inc. claims to have
redesigned network

available bandwidth with

04.12.2007Vista Users: Beware of the Firewall
The Internet Engineering Task
Force recently held its 68th
meeting in the
beautiful-but-cloudy city of
Prague. At that meeting, Dave
Thaler, who works at Microsoft
and is a member of the IETF's
architecture board, the IAB,
talked about what Microsoft
ran into when revising the
Windows TCP/IP stack for
Vista. The result: Network
connectivity may fail when you
try to use Windows Vista
behind a firewall device
(Microsoft Knowledge Base
article 934430).
What's this all
about? There are actually two
issues at play.
After XP shipped,
Microsoft wanted to take the
opportunity to add some new
TCP features to
Longhorn/Vista's IP stack.
The most troublesome new
feature is ECN, or Explicit
Congestion Notification. ECN
is specified in RFC 3168,
published shortly after
Windows XP's release in 2001.
The idea is that when there is
congestion on the network
because too much traffic wants
to flow through a certain
connection, it would be good
if the router would tell the
hosts sending all this traffic
that there's congestion so
they can slow down a bit.

05.04.2007How to fix Vista's network bottlenecks
As much as I enjoy using Vista, I've definitely noticed that in some networking activities, it definitely seems to struggle. Particularly compared
with Windows XP.
For the most part it's not a problem - I just assumed that Vista's beefy network stack was responsible, and made a
mental note to fix it at some point. And then forgot.
But recently I encountered a really frustrating problem. Using Remote Desktop
Protocol (RDP) to connect from a Vista Enterprise machine to a Windows 2003 server, the performance was so woeful that I was starting to worry whether
there was a problem with the server.
As it happens, my fears about the server were unfounded, but the thought that Vista's networking
stack was to blame turned out to be correct. The Next Generation TCP/IP stack in Windows Vista supports something called Receive Window Auto-Tuning.
This is nothing to do with the RDP "window" you see on the screen, but rather a TCP buffer which TCP/IP clients use to ensure smooth
transmission.

19.11.2008Configuring Windows Server 2008 as a Remote Access SSL VPN Server (Part 1)
Remote Access is one of todays big things. As an increasing number of people need access to information stored on work and home computers, the
ability to access that information from anywhere is critical. Gone are the days when you could say Ill get that information to you when I get to my
computer. You need that information now if you want to be competitive in todays business environment.
In the stone age of
computing, the way to remotely access information on your computer was to use a dial-up connection. RAS dial-up connections worked over regular POTS
(Plain Old Telephone Service) lines and had speeds that ranged up to around 56kbps. Speed was a major problem with dial-up RAS connections, but an
even bigger problem was the cost of the connections when a long distance number was required for access.

21.07.2007Disable Windows Server 2003 SP2 Scalable Networking Pack features
Michael Platts: As you may know, Service Pack 2 for Windows Server 2003 included the
Scalable Networking Pack (or SNP) which allowed for increased performance in many situations by allowing some TCP functionality
to be handled by the network driver and network adapter instead of the Windows TCP/IP stack itself. This functionality was enabled by default in
Service Pack 2.
There have been some problems seen in some environments where Windows Server 2003 SP2 has been deployed on
systems that support the SNP features. Issues like this have been discussed in several previously published Knowledge Base articles.
There is now a new update available that will turn off the Scalable Networking Pack features on Windows Server 2003 Service Pack 2
systems. The article lists a number of symptoms that have been seen when Windows Server 2003 SNP is enabled and links to download the update for
x86, x64, and Itanium-based systems:

05.08.2008Configuring the Windows Server 2008 Terminal Services Gateway (Part 1)
Thomas Shinder: Microsoft security administrators have always been a bit wary of publishing Terminal Servers to the Internet. And for good reason
there was no ability to pre-authenticate connections or use policy to determine which users could access which Terminal Servers. The lack of
pre-authentication was an especially difficult problem. Without pre-authentication, anonymous users could leverage their anonymous connections to
compromise the published Terminal Server. A compromised Terminal Server is perhaps the most dangerous exploit possible against your network, as the
attacker has access to a full operating system to launch his attacks.

01.10.2008Trend Micro Warns Of Server Antivirus Flaws
Trend Micro has patched a pair
of remote code execution
vulnerabilities in
ServerProtect, its
server-based antivirus
software, that could open the
door for attackers to gain
control over affected
machines.
Both are
stack-based buffer overflow
bugs affecting ServerProtect
For Windows version 5.58,
Trend Micro said in a Tuesday
advisory.
The first
flaw stems from the failure of
the "TmRpcSrv.dll" library
to check user input before
copying it to memory, Symantec
said in a Deepsight Threat
Management System advisory.
The bug affects the
"EarthAgent.exe" daemon on
TCP port 3628, and an attacker
could exploit it by sending
malicious code to a server
with ServerProtect installed,
according to Symantec.
The second
vulnerability exists in the
"AgRpcCln.dll" library and
can be used to trigger a
malicious RPC request to the
"SpntSvc.exe" service, which
is on TCP port 5168, Symantec
said.
