I am running Vista Home Basic with SP1 on a 32 bit PC. Whenever I try to go online using a good ethernet cable to my modem (I know both of them are good because THIS PC is using the same cable and modem) I get the 'Internet Explorer cannot display the webpage' msg. If I then click on Diagnose Connection Problems I get the msg Network Diagnostics cannot run because the Diagnostics Policy Service is not running. If I go to Services.msc, and attempt to start the service I get Error 5: Access is denied. There are no dependencies on this service If I hover the mouse over the network icon in the notification area, it reads, "Connection status unknown. The dependency service or group failed to start". If I try to start DHCP Client, I again get Access denied.. I ran a full Malwarebytes scan and it found nothing wrong. I did a system restore to several days before the problem, but even though the restore completed successfully, it didn't change my (non)results. I have run sfc /scannow as well as chkdsk /f. Scannow reported that it found some problems but was unable to fix all of them. The CBS.log is not something I'm able to interpret. I have run chkdsk /f about 6 times, sometimes in safe mode, sometimes normal. It always seems to find and correct the same 10 or so errors. Neither chkdsk or scannow helped with the connectivity issue. The Network and Sharing Center does not display the familiar PC monitor icon with a line to the Network and another line going from the Network to the Internet. Instead it just has the word Unknown with the caption the depencency or groiup failed to start I have heard that this might be due to a permissions issue. So I used regedit and navigated to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and right click on Dhcp. I don't have Permissions available. I mean I don't even have the WORD Permissions I gone run msinfo32 and verified that I am not suffering from Winsock2 corruption, but I have run netsh winsock reset just the same. And then rebooted. Nothing. I have tried ipconfig /release (and /renew), but with both commands I get the msg that the RPC Server is unavilable. However, in Services, the Remote Procedure Call is Started I have checked device manager. No red or yellow areas. Network adapter and driver functioning correctly. Additionally I have downloaded and installed Process Monitor on the PC, but the amount of information displayed is overwhelming, and I'm not sure what to check. Every time I try to start DHCP I get about 200 lines of info on the screen. When I open a command prompt and run ipconfig /all, I get the bogus ip address of 169.254.xxx.xx and a Default Gateway of 0.0.0.0. This was working just fine last week. I hadn't shut it off for days. Then I shut it off. It hasn't worked since. Do I have to reinstall Vista because of a service issue? How could it have gotten so corrupted?

Hi, Did you check the steps in the following KB article? Some services do not start in Windows Vista You can try the following steps to troubleshoot the issue. 1. Temporarily disable Firewall and third party antivirus program on the computer for a test. 2. Boot the system to Safe Mode with networking and see if the issue persists. If not, please also boot to Clean Boot environment to determine the possible cause. 3. Update or reinstall the NIC driver and update the router’s firmware. 4. Assign a static IP address for a test ========================= a. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. b. Right click on the connection that you use for the local connection, and then click "Properties". c. Click “Continue” to verify the administrator permission. d. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". e. Select “use the following IP address”. Manually set “IP address” (For example, if your router IP address is 192.168.1.1, we can type the IP address as 192.168.1.22. If the router IP address is 192.168.0.1, we should type in 192.168.0.22.) Manually set “Subnet mask” as 255.255.255.0 (Note: We can use this address as the default subnet mask.) Manually set “Default gateway” (Note: Default gateway is the IP address of the router.) Manually set “preferred DNS server” (Note: Preferred DNS server is also the address of the router.) f. Click “OK”. If the issue persists, it can be caused by the damaged system files. We may need to recover the system with the Vista DVD.
