He was appointed as caretaker player-manager at Kidsgrove alongside Terry Hillman after they sacked Dave Nolan on 14 November 2002 and was offered the job permanently on 31 December 2002.
He resigned as manager on 28 March 2003, with Bernard Taylor being appointed as his successor.
Following his spell at Kidsgrove manager, Porter returned to Port Vale as a youth coach.
In December 2004, Porter made a playing comeback when he replaced Levi Reid early in Vale's 3–1 win over Tranmere Rovers.
Over the next two seasons he made three more Football League and two FA Cup appearances under manager Martin Foyle, his former teammate at Vale.
A move to Nantwich Town in March 2006 was blocked by Foyle as the club were short-staffed.

Following these brief cameos Porter settled down to his duties as youth coach and achieved a large amount of success with the youth team in 2007 and 2008.
In the summer of 2007 the youth team entered the prestigious Irish youth tournament the Foyle Cup, beating Bournemouth 1–0 in the under-18s final to claim the trophy.
Porter also steered the team to a club record quarter final appearance in the FA Youth Cup, beating Premier League academy sides Bolton Wanderers (3–2 at the Reebok Stadium) and Tottenham Hotspur (1–0 at Vale Park) along the way, before losing to eventual finalists Chelsea 5–2.

Porter's charges then won the Midland Youth Cup for the first time in decades, beating Lincoln City 6–5 on a penalty shootout after a 1–1 draw at Sincil Bank.
He had also taken charge of the reserve side for the majority of the 2007–08 season, and managed to finish second in The Central League Midland Division in front of several higher-placed clubs and clubs with youth academy status.

Following Lee Sinnott's departure as manager, Porter and Dean Glover were appointed as caretaker managers on 23 September 2008.
He was in the running for the role on a permanent basis, but it was eventually handed to Glover on 6 October.
Porter departed as manager of the Port Vale youth team on 24 December.
He later cited his reasons for doing so as being rejected for the managerial position earlier in the season and also not being offered the role of assistant manager, despite his success with the youth team, coupled with a need to advance his career.

He teamed up again with Martin Foyle after being appointed as York City's assistant manager on 30 December.
Glover was sacked as Vale manager in May 2009 and Porter applied for the vacant position once again.
However chairman Bill Bratt was determined to hire a manager of experience and so Porter was not considered for the role.
He took over as caretaker manager at York on 24 September 2010 following Foyle's resignation and his first game in charge was a 3–1 victory away at Tamworth the following day.
After two weeks in charge, on 6 October 2010, Porter also left the club.

On 12 February 2011, Porter turned out for Alsager Town in their North West Counties Football League Premier Division 2–0 defeat to Glossop North End.
The 42-year-old played for the full ninety minutes as a favour to the club, who put out a makeshift first eleven after a period of disarray.
Later in the year he was appointed as a youth coach at Stockport County.

In June 2012, Foyle appointed Porter as his assistant when he took over his new role as manager of Hereford United.
He left the club when Foyle departed as manager in March 2014.
The following year he began helping Foyle in his dual roles at Port Vale and Northampton Town, coaching the under-11's at the Port Vale academy and doing regional scouting for Northampton.
