IDM?
I have never SEEN so many errors, is this Windows 8.1, or just 8?
There are so many errors in the log, that there are no NON error entries, I kind of need to see what services were successful too.
This is what I garner from your error log:
Looking at the beginning of it, it appears to be errors during installation - If this was 8 or 8.1 updated through the web and not from a disk, I think I understand why there are so many reported problems: The Log is SOLID ERROR messages.
Looking back up at the top for the last few days of use, well you have an IP configuration conflict, your machine is conflicting with another machine on the network for an IP address resolution. So, if you are running two machines on one LAN and they keep conflicting like this, I would assign each one it's own static IP address.
You can usually set this up in the Router, I did it with my Linksys WRT110- Just clone the mac address of each PC into the Router Config, and then assign the MAC address of each machine to a specific IP address on the LAN.
For instance, this computer I have set for 192.168.1.100
And my Media PC is 192.168.1.101
And those are locked in to the router, by default they WILL resolve to those addresses.
If you don't understand or can't do this, if you cant get to your Router, then just disable the other computer on the LAN
I might need to know more, what kind of service, what ind of Router, connections, etc.
