Can’t configure maximum concurrent SMB requests in XP
By default, concurrent SMB commands in Windows XP are limited to 10, the same as the limit on concurrent network connections. This can cause a problem in certain circumstances where you have long-term SMB requests that remain open until answered. It can result in error messages and other requests going unanswered. If you have this problem, there is a hotfix that will let you increase the maximum number of concurrent SMB commands up to 255 in XP with SP2. To find out more, see KB article 926646.
