no, MKDIR is *not* required, also write access is *not* required. Assuming a directory with a name that starts with "A" exists and that is at least 14 chars long, this pattern will trigger the overflow: NLST [Ax206]*/../A*/../A*/../A*/../A*/../A*/../A*/../A*/\r\n At least on win2k3. Therefore, the workarounds for kb975191 on microsoft.com are wrong. Guido Landi Vladimir '3APA3A' Dubrovin wrote: > Dear Thierry Zoller, > > I think yes, MKDIR is required.
