We started noticing a problem with our Windows 7 clients accessing files stored on a 2008 R2 server. Specifically we saw that the network directory was not displaying updated content on some of the clients. Further research suggests that adding the following keys resolves the problem. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters FileInfoCacheLifetime FileNotFoundCacheLifetime DirectoryCacheLifetime My question is what effect will setting the value of these keys to 1 have on our network. I know by default SMB2 caching is suppose to poll every 10 seconds. So by dropping this down to 1 second are we going to notice a significant amount of additional bandwidth or requests to the file server? I dont want to roll out this change and have our network or file server overwhelmed. I appreciate any information anyone has regarding this change.
