 In the end i found two accounts with invalid smtp addresses which the logs identifed easily.

Anyway I was googleing for answers as any resourceful tech does.

I came across this Microsoft KB Article 933860.

DFS failover does not occur when a client computer that is running Windows Vista tries to connect to a DFS root server that is unavailable, and you receive an error message: “System error 1214 has occurred”

Now these were not the exact symptom’s I was experiencing, but sounded similar. Anyway I contacted MS for the hotfix’s for Vista x86 and x64, and the issue is now resolved.

After several drinks, one of the men had to use the rest room.

Those who remained talked about their kids. The first guy said, “My
son is my pride and joy. He started working at a successful company at
the
bottom of the barrel. He studied Economics and Business Administration
and
soon began to climb the corporate ladder and now he’s the president of
the
company. He became so rich that he gave his >best friend a top of the
line Mercedes for his birthday.”

The second guy said, “Darn, that’s terrific! My son is also my pride
and joy.
He started working for a big airline, then went to flight school to
become a pilot. Eventually he became a partner in the company, where he
owns
the majority of its assets. He’s so rich that he gave his best friend a
brand new jet for his birthday.”

The third man said: “Well, that’s terrific! My son studied in the best
universities and became an engineer.Then he started his own
construction company and is now a multimillionaire. He also gave away
something very nice and expensive to his best friend for his birthday: A
30,000 square foot mansion.”

The three friends congratulated each other just as the fourth returned
from the restroom and asked: “What are all the congratulations for?”

One of the three said: “We were talking about the pride we feel for
The successes of our sons. …What about your son?” The fourth man
replied: “My son is gay and makes a living dancing as a stripper at a
nightclub.”

The three friends said: “What a shame…what a disappointment. “

The fourth man replied: “No, I’m not ashamed. He’s my son and I love
him.

And he hasn’t done too bad either. His birthday was two weeks ago, and
He received a beautiful 30,000 square foot mansion, a brand new jet and
a top of the line Mercedes from his three boyfriends”.

In microsoft outlook, interface not registered = a most sucky error

Step 1: Create an access-list that matches my file server (172.30.100.11), but only during the day.

Router(config)# time-range DAY (creates a new time range)
Router(config-time-range)# periodic weekdays 6:00 to 22:00 (matches weekdays from 6:00am to 10:00pm)
Router(config-time-range)# periodic weekend 6:00 to 22:00 (matches weekends from 6:00am to 10:00pm)
Router(config-time-range)# exit
Router(config)# ip access-list extended SERVER
Router(config-ext-nacl)# permit ip host 172.30.100.11 any time-range DAY (matches my server during the time-range I specified above)
Router(config-ext-nacl)# exit
Router(config)#

Step 2: Create a class-map (used for QoS) that matches the SERVER access-list we just created.

Router(config)# class-map MATCH_SERVER (MATCH_SERVER is just the name)
Router(config-class-map)# match access-group name SERVER (ties in the access-list above)
Router(config-class-map)# exit
Router(config)#

Step 3: Create a policy-map (used for QoS) that throttles the bandwidth.

Router(config)# policy-map LIMIT_SERVER (creates the policy)
Router(config-pmap)# class MATCH_SERVER (applies policy to this class)
Router(config-pmap-c)# police 80000 (limits bandwidth to 80Kbps)
Router(config-pmap-c)# exit
Router(config-pmap)# exit
Router(config)#

Step 4: Apply the new policy to the incoming interface (the one connected to my LAN, not the Internet).

Router(config)# interface fa0/0
Router(config-if)# service-policy input LIMIT_SERVER 

 this is the command to clear your arp cache

netsh interface ip delete arpcache

NBAR configuration to drop Skype packets

class−map match−any p2p
match protocol skype

policy−map block−p2p
class p2p
drop

int dialer0
description Internet interface
service−policy input block−p2p

If you are unsure about the bandwidth eating applications being used in your organisation. you can access the interface connected to the Internet and configure following command

ip nbar protocol-discovery.

This will enable nbar discovery on your router.

Use following command

show ip nbar protocol-discovery stats bit-rate top-n 10

it will show you top 10 bandwidth eating applications being used by the users. Now you will be able to block/restrict traffic with appropriate QoS policy.

we can also use ip nbar port-map command to look for the protocol or protocol name, using a port number or numbers other than the well-known Internet Assigned Numbers Authority (IANA)-assigned) port numbers.

You can also create custom definitions using this command.

ip nbar port-map protocol-name [tcp | udp] port-number

Up to 16 ports can be specified with this command. Port number values can range from 0 to 65535

TPG require you to use PPPoE and PAP not CHAP for authentication.
Also you are required to use the full tpg username ***@L2TP.tpg.com.au

Relivant parts of the config are below.

interface ATM0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
pvc 8/35
encapsulation aal5snap
protocol pppoe

interface Dialer0
