Big problem with internet explorer and ftp proxy on bm3.7.

Sever NW6SP4, BM3.7SP3
FTP Proxy configuration:
User Authentication - NONE
Access Rules - Allow Any Any.

IE5.5SP2 on WinNT/2000 configuration:
FTP proxy - ip_address:21
"Enable folder view for FTP sites" - OFF
"Use passive FTP" - ON

Everything works fine from CuteFTP or DOS prompt. But when I'm trying to
connect via IE - there is no response from server. User cannot use
anything except IE.

Looked through Novell and MS knowledgebase - nothing what can helps. Any

Sincerely Yours,
Ilya Genkin
