Yes, <subj> is well worn by now, but.. On my testsetup with both a 100Mbit and a 10Mbit segment, clients hardly ever yanks out the 'server has closed connection' popup.

On job, with almost identical setup, occationally OE/Outlook clients will complain. All internal segments are switched 100Mbit behind a Linux ipchains firewall/router, but one segment is still 10Mbit, hubs only, with maybe 5-6 printers having too little ram and clients printing directly to those.

On this segment, O/OE clients quite often produce the popup. My feeling is that the segment may be poorly designed and causing this annoyance. Of cause, it's a simple job to improve the condition, and it will be done; just like to know if anyone else have had semilar experiences?
