I have several hundred servers that I need to change the description on. I was hoping to use this command to do it. (I do NOT want to just change the registry because it requires that the servers be rebooted) Change the comment displayed in My Computer (detail view) NET CONFIG SERVER /Srvcomment:"YourText" Before using the /Srvcomment option see Q128167 http://support.microsoft.com/?kbid=128167 So if I use that command, it says that it will disable "autotuning" What exactly does auto-tuning do? What are the ramifications of this? I tried searching around and didn't really find anything other than TCP/IP tuning, which I don't believe is the right thing.

Hi, As explained in the KB, "auto-configured" is to calculate and set server configuration parameters. For example, if you add memory to your computer, Windows kernel and services need to change their parameters to use additional memory. With "autotuning", server will change its parameter automatically. If "autotuning" is disabled, some service parameters may not be updated in time. Thanks.

We were looking for something more specific than "some service parameters". This is very ambiguous, as is the documentation. Are there any specific keys in the registry we should be aware of that are not going to be updated that we should update, in the case of a memory upgrade?

To find all parameter of Server service, please open regedit and navigate to the following location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters Note, there is a AutotunedParameters key. I tried to add memory to a VM and compare LanmanServer Registry Key, but only found there is no change. I think we don’t need to worry about it since we know they are all stored in Registry and we can edit them manually if necessary. Thanks.
