    According to the manual, none of *_channel_of_descr works on sockets 
on Windows 95/98/Me. What are you using ? As for me, to avoid that kind 
of problems, when writing Amble I made my own send/receive functions. 
Send is trivial (Marshal to string and Unix.write), receive is also 
pretty simple :

let receive_message fd =
     (* 1 - allocate and read the header *)
     let hs = Marshal.header_size in
     let headerbuf = String.create hs in
     let hlen = Unix.read fd headerbuf 0 hs in

     (* 2 - prepare the buffer as a string that has the same size as the 
message
      *     and copy the header in the beginning
      *)
     let ds = Marshal.data_size headerbuf 0 in
     let buf = String.create (hs+ds) in
     String.blit headerbuf 0 buf 0 hs;

     (* 3 - receive the rest of the message (data part) *)
     let dlen = Unix.read fd buf hs ds in

     (* 4 - decoding (unmarshalling) *)
     Marshal.from_string buf 0
