Hi, I was trying to optimise win server 2003 entreprise to be used as a workstation, as I've heard this one is much faster than Xp. Also I was quite discouraged by the over-bloated vista, so I was looking for something more recent than xp, without the slowness of vista (on my system..) Anyway, I've made many try to build isos and then test them in vmware.... Then I tryed to refine settings, and to tweak all service of the system. I've especially followed the recommendations from this site: http://www.blackviper.com/WinXP/service411.htm All the advices were for xp pro. Since I got win server 2003 I thought that disabling any service that's not in xp pro would be fine. I think it is the whole new list of service added: The problem: it seems to install fine until the system have to start for the first time after the install. And BAM, just before I can even see my new fresh desktop I get a BSOD. The problem does not occur if I set to default all service I have desactivated. Here's the list of service leading to BSOD when desactivated: [services2] AeLookupSvc,4 Browser,4 Dfs,4 TrkSvr,4 DNSCACHE,4 NtFrs,4 HidServ,4 IsmServ,4 kdc,4 LicenseService,4 MountMgr,4 NetLogon,4 NetBT,4 NLA,4 xmlprov,4 PartMgr,4 RSoPProv,4 RemoteAccess,4 LanmanServer,4 ScardSvr,4 sacsvr,4 LMHosts,4 Themes,4 UPS,4 vds,4 WebClient,4 SharedAccess,4 W32Time,4 WinHttpAutoProxySvc,4 See my attachements for the full settings I use. Could you help me to tweak in a safe way the remaining setting without having a BSOD ? It seems I 'll give up, and leave all services as default (almost ) if I can't get an answer. I can't make hundred try under VMWARE in order to locate why I get this annoying BSOD. The worse thing is all that services are not needed in safe mode (using the bare minimum of services) so then w hy without them I can't install ? thanks tell_me_why.ini
