On all of the 15 XP Pro workstations, many services fail to start automatically, including the network browser service, on a small business server 2003 network.
Despite this most network programs work normally and existing mapped network drives are usually accessible. My network places however cannot be browsed unitl the network browser service is manually started. Other problems caused by this issue, which seemed to co-incide with last months Windows updates ,are as follows.
1) The Windows firewall is now controlled by Group Policy, resulting in a 'firewall may be disabled' error message appearing on startup.
2) SBS Exchange appears off-line at regular intervals, although it then manages to re-connect and synchronise ( as Exchange is working in cached mode this does not cause any serious problems ).
3) Data Execution Prevention error messages are appearing on startup, which then seem to be resolved by changing the DEP settings to 'turn on for all programs, except..." option
4) The desktop screen display on many of the workstations changes to a basic 'Windows Classic' view i.e. the Start Button changes to the basic button icon, the background changes etc. ( N.B. roaming profiles are not enabled ).
5) The anit-virus software has problems updating on some of the workstations, although there are no viruses found and eventually it does manage to update.
6) Network drives sometimes have a red cross through them in My Computer, but when double clicked they still link to the server
For reference, all PC's are relatively new, of good specification and the server is also very highly specified . The network infrastructure is fairly new and includes a fast ethernet 24 port switch.
How can the above issues be resolved?
