SYMPTOMS

Under the following conditions, you may receive one of two different error messages:
  • You try to use a share on a Windows XP-based computer from another client computer.
  • Your domain account is a member of more than 180 groups.
  • You try to connect to the share by using a universal naming convention (UNC) name such as \\computer name\share name.
Under these conditions, you may receive either of the following error messages:
Windows cannot find \\computer name
computer name is not accessible [...] you might not have permissions to access computer name. More data is available.

CAUSE

The redirector requires that tokens that are used for authentication cannot be larger than four kilobytes (KB). Membership in a large number of groups can result in a token that is more than four KB, and this may cause the remote connection to fail.
