I upgraded my spare FC3 workstation to FC4 two days after FC4 was released. The upgrade went smoothly (once I had "good" media - had to reburn 2 of the 4 CDs). I edited my /etc/hosts file to change the name of the workstation. Even after I did that, it still takes forever on startup on the sendmail portion. And my wireless/wired router shows "unknown" for the host name. But that's not the worst, as long as this FC4 workstation is turned on, none of the other workstations/laptops on my network can't access the internet. Everything slows to a molasses like crawl or stops functioning at all. Once I turn off the FC4 workstation, the network reverts back to normal (100 MB wired/11 MB wireless). I scanned briefly the log files but couldn't find anything interesting or a smoking gun. I even reviewed my router's log files - but nothing strange there either. Any ideas on what could be the issue? Thanks, Jon Moss __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
