Over the past 6 months, our APPX login times have steadily lengthened. 


Normally this symptom is due to a growing USAGE file.  Other likely events;


- network traffic in general has increased on your network

- more users in APPX

- more PC’s on your network

- do you have the APPX client stored on a local disk on each client PC, or
  are  you retrieving it from the network any time someone logs in?  (See the
  WinAppxD FAQ, ftp.appx.com/pub/documents/winappxd-faq.txt, section 2.12: 
              "Automatically update Presentation Client".)

- It's also possible that you have a DNS or WINS issue
