Being asked to add support for Realteks Fast Ethernet PCIe NICs to my RTL8111 driver I got tired of answering the same old question again and again so that I finally decided to write a separate driver for these chips and to make a few of you guys and gals happy. As of now the driver supports the. Disabling that functions is a feature of most ethernet cards, it's called 'TCP checksum offload'. Under Linux you have to execute: 'ethtool -K eth0 rx off tx off' - replace eth0 if different name is used, and consult the man pages for 'ethtool'.

Like most Sys Admins, my job includes managing both Linux and Windows machines. This is the start of a two-part series regarding tweaks I have found for networking in each type of system. First up: Windows.I have labeled my findings based on where you'll find it: either as an operating system feature, or in the device manager of the Ethernet adapter you're using.

Driver: Interrupt Coalescing / Moderation Driver: Offloading (IP / TCP / UDP) for layer 3 or 4 protocols; there is also a feature on some adapters. These features are meant to reduce CPU overhead by having the network adapter do more of the work: however, a lot of network adapters are sub-par, and there is no harm in having the CPU do these tasks (disabling the offloads) for anything short of a server-grade adapter. The exception would be: that seems to be easily doable by any hardware. 2003 & Older: SMB tweaking that should improve file sharing performance on older Windows systems: they will have little or no impact on newer systems, for they use. XP & Newer: Automatic IPv6 Tunneling, I was fortunate to question a Cisco engineer that took credit for having Windows implement automatic tunneling with XP and newer: he believed that providing IPv6 access, 'native' or not, would spur application developers to honor API changes and continue to embrace the new protocol.

Now that 2010 is almost out: has been maligned by and for breaking website access; can be hard to work with; can be hit or miss (Microsoft does host some servers for use); and that desired application uptake has been largely ignored by the likes of, Steam, and others. The speaker can be forgiven that his intentions went awry, when quite a few people (Linux and Windows) think the best way to handle IPv6 is to. Fortunately, you don't have to slay the IPv6 beast: its a known fact we'll be living with it, like it or not.Gigabit adapters in particular implement new algorithms to try to accommodate different forms of network traffic: especially when a good portion of it may not need that kind of speed (think web-facing adapters on 10/100 lines). However, it has been my own experience that Quickbooks can be particularly jumpy with this feature enabled. It goes by several different names (depends on the vendor) but you should only need to leave this on if you're using a gigabit interface on an Internet-facing server. Netsh interface ipv6 6to4 set state state=disablednetsh interface ipv6 isatap set state state=disablednetsh interface ipv6 set teredo disablefunction.,.

Was introduced. I use this 'Compound TCP' when I can on the newer systems: fortunately, it has been backported to the 2003-based systems via. Vista & Newer: Standard Networking Tweaks, and: the latter is a function of Windows that does partial TCP offloading when able. At the 'administrator' command prompt.2. On Windows XP systems, you can also disable the 'IP Helper' service: however, you'll lose use of the3. If you want to use IPv6, and your ISP doesn't have it, consider free (and stable) tunnel services fromXP x64 & Server 2003: Compound TCPWith the Vista networking stack, a1. I make prudent use of Compound TCP,netsh interface tcp set global congestion=ctcpnetsh interface tcp set global time=enablednetsh interface tcp set global chimney=enabledfor troubleshooting purposes; it can be disabled with the following command.2.

I prefer not to usenetsh interface ipv6 set privacy state=disable3. There is an additional tweak that can help deal with proper traffic routing: however, many routers don't implement it correctly, and Battlefield Heroes doesn't like it at all. Use at your caution.netsh interface tcp set global ecn=enabledAnd there you have. My list of favorite tweaks. Next up: Linux.

Our corperate office has implemented a new document retention policy. Partof the policy requires users to contact the IT department if they want a newfolder created in their Exchange mailbox (Each folder must have a retentionpolicy setup by the IT dept using Symantec Enterprise Vault). We've beentold that we have to come up with a way to disable our users ability tocreate folders in their mailboxes. I was wondering if anybody has any ideason how to set this type of security on Exchange. I can't see how to do itvia 'Mailbox Rights'.

Thanks for the help.i d.In the older version of Office when you opened an excel or other officedocument that had a macro in it - you would get a pop up and the opportunityto enable or disable it. Is there a way to get that same pop-up in 2007?Try the following.Click Trust Center, click Trust Center Settings, and then click MacroSettings.Then 'Disable all macros with notification'.'
