In IE6 we have on some PCs the problem that the session data will not saved:

First page:

session_start();
$User = "root";
session_register(User);

Second page:

session_start();
echo "$User";

Now nothing will displayed...   :-(

This Problem occures only in IE6 an never in IE5.x

Hmm. I use IE6+Linux/Apache and I don't have problem.
Could you look into packets using sniffer? and see if there is any difference with IE6 and IE5.

Ehtereal works on a lot of platforms and very easy to use.

I thing, you forgot to place quotes around variable name
Instead of 
session_register(User); BAD
use
session_register("User"); OK

If the session info is saved as a file, instead of a file called sess_<cryptic session-id>, you will find a file named 'sess_null'.

-rw-------   1 myuid mygid 1535549 Dec 10 12:57 sess_null

I'm running php4.3.4 on apache2 on a solaris8 box.
Browser is Internet Explorer 6.0.2800.1106CO.

Session management troubles happen only with IE6, but runs fine with e.g. Mozilla 1.5.

The problem is *very*critical* for us, because _every_ user who logs on with an IE6 gets user permissions from the sess_null. sess_null could be the admin's session.

Vice versa it's also a problem if the first user to create a sess_null was not-privileged, and the subsequent admin logon is "castrated" to the non-privileged level.

This problem occures only, if the hostname of the server contains an "_" (underscore). We have changed the hostname now.

FYI, hostnames with a _ in there are not even allowed. From Appendix 1 of RFC 882:

<domain> ::=  <subdomain> | " "

      <subdomain> ::=  <label> | <subdomain> "." <label>

      <label> ::= <letter> [ [ <ldh-str> ] <let-dig> ]

      <ldh-str> ::= <let-dig-hyp> | <let-dig-hyp> <ldh-str>

      <let-dig-hyp> ::= <let-dig> | "-"

      <let-dig> ::= <letter> | <digit>

      <letter> ::= any one of the 52 alphabetic characters A through Z
      in upper case and a through z in lower case

      <digit> ::= any one of the ten digits 0 through 9
